Spatio-temporal analysis of power deposition and vibrational excitation in pulsed N2 microwave discharges from 1D fluid modelling and experiments

Vibrational excitation of N2 beyond thermodynamic equilibrium enhances the reactivity of this molecule and the production of radicals. Experimentally measured temporal and spatial profiles of gas and vibrational temperature show that strong vibrational non-equilibrium is found in a pulsed microwave discharges at moderate pressure (25 mbar) in pure N2 outside the plasma core and as an effect of power pulsing. A one dimensional radial time-resolved self-consistent fluid model has been developed to study the mechanism of formation of vibrationally excited N2. In addition to the temperature maps, time-resolved measurements of spontaneous optical emission, electron density and electron temperature are used to validate the model and the choice of input power density. The model reveals two regions in the plasma: a core where chemistry is dominated by power deposition and where vibrational excitation starts within the first ∼10 µs and an outer region reliant on radial transport, where vibrational excitation is activated slowly during the whole length of the pulse (200 µs). The two regions are separated by a sharp gradient in the estimated deposited power density, which is revealed to be wider than the emission intensity profile used to estimate the plasma size. The low concentration of excited species outside the core prevents the gas from heating and the reduced quenching rates prevent the destruction of vibrationally excited N2, thereby maintaining the observed high non-equilibrium.

Plasma assisted pulsed laser deposition of WO3 films for thermochromism

Tungsten trioxide (WO3) is one of the extensively investigated transition metal oxides. Its excellent chromogenic properties make WO3 promising for a variety of scientific and technological applications. We report a new method for reactively depositing WO3 films by plasma assisted pulsed laser deposition that combines electron cyclotron resonance microwave discharge and pulsed laser ablation. The plasma formed during film deposition was spectroscopically characterized by optical emission measurement, revealing that the plasma contains high density of reactive gaseous oxygen and tungsten species which are essential for efficiently synthesizing WOx precursors and depositing WO3 films. The structure of the deposited films and the effect of post-deposition thermal annealing on the film structure were characterized by X-ray diffraction and Raman spectroscopy. The as-deposited WO3 film appears amorphous in nature. Annealing resulted in the growth of crystalline grains and the improvement in the crystallinity of monoclinic WO3. Optical properties of the prepared WO3 films were studied by measuring ultraviolet–visible–near infrared transmission spectra. With the increase of annealing temperature, the WO3 films show a continuous change in color, decline in transmittance, red shift in absorption edge, and narrowing in band gap, clearly manifesting the thermochromic features of the deposited WO3 films.

Luminescence performance of Dy3+ ions incorporated modifier reliant boro-tellurite glasses for white light applications

A diverse array/unique set of Dysprosium (Dy3+) activated alkali boro-tellurite glasses were synthesized for the current study using the conventional approach of glass fabrication, and its potential for photonic applications were explored utilizing optical absorption, emission, and decay measurement methods. In the interest of assessing the Rare Earth (RE) ions bonding behavior with the neighboring metal ligand site, and to establish the glasses ionic/covalence nature, bonding parameters (δ) and Nephelauxetic ratios were computed from the absorption band locations. For the as-prepared samples, the Judd-Ofelt parameters and oscillator strengths were determined in order to scrutinize the uniformity of the ligands surrounding Dy3+ ions. The calculated JO values consistently pursue Ω2 > Ω4 > Ω6 pattern for all samples, indicating their asymptotic character. When excited at 387 nm, the emission spectra demonstrate three intense transitions; 4F9/2→6H15/2, 4F9/2→6H13/2 and 4F9/2→6H11/2. Among them, strong yellow emission was observed owing to the increased transfer of electrons to 6H13/2 level. Besides, using JO parameters, radiative parameters were determined which was followed by lifetime studies to actualize the novel applications. The photoluminescence spectra were employed to estimate the CIE coordinates (x, y) and Yellow/Blue ratio, furthermore the (x, y) values were used to calculate the colour purity followed by colour correlated temperature (CCT). This demonstrates that the prepared samples have the ability to emit neutral white light.

Impact of Fe-doped H2/O2 flame equivalence ratio on the fate and temperature history of early particles

The temperature and species concentration history experienced by the gas-borne nanoparticles during their evolution in the flame has a major impact on their size, morphology, composition, and crystallinity. In our recent work (Combust. Flame, 244 (2022) 112251), we have reported optical emission measurements of a Fe(CO)5-doped H2/O2/Ar fuel-lean (ɸ = 0.5) flame, revealing that the temperature of the early-formed nanoparticles exceeds the gas temperature by several hundred degrees, while the particle volume fraction increases sharply, followed by rapid disintegration in the reaction zone. This behavior, modeled by single particle Monte-Carlo simulations indicates involvement of heterogeneous reactive processes at the particle surface, such as particle reduction and oxidation, growth and etching. Within the refined approach of the current study, reactive and non-reactive collisions were treated consistently, assuming rapid thermalization between the impinging molecule and the particle, with subsequent random energy sampling to determine reactivity. In the present work, we test the limits and validity of the heterogeneous flame-particle interaction model by manipulating the oxidation–reduction and growth-etching balance by varying the equivalence ratio (0.25<ɸ<1.5). For the entire range of equivalence ratios studied in experiments and simulations, we find a deviation between the particle and gas phase temperatures with significantly higher particle temperature, which is continued until a full degree of iron oxidation within the particle (O/Fe ratio=3/2) is reached. Validating the simulations against the measurements of particle temperature and volume fraction over a wide range of equivalence ratios, emphasized the necessity to account for gas-phase Fe-atom concentration depletion. We incorporated nucleation theory to estimate initial cluster population, linking Fe-concentration variation in the gas phase and the stochastic particle evolution model. The surface reaction parameters in our current work were updated using density functional theory literature data, and validation of the model predictions against experimental data, across the entire range of equivalence ratios.

Synthesis, Electrochemical and Photochemical Properties of Sulfanyl Porphyrazine with Ferrocenyl Substituents.

Ferrocene is useful in modern organometallic chemistry due to its versatile applications in material sciences, catalysis, medicinal chemistry, and diagnostic applications. The ferrocene moiety can potentially serve many purposes in therapeutics and diagnostics. In the course of this study, (6-bromo-1-oxohexyl)ferrocene was combined with dimercaptomaleonitrile sodium salt to yield a novel maleonitrile derivative. Subsequently, this compound was subjected to an autocyclotetramerization reaction using the Linstead conditions in order to obtain an octaferrocenyl-substituted magnesium(II) sulfanyl porphyrazine. Following that, both compounds-the maleonitrile derivative and the porphyrazine derivative-were subjected to physicochemical characterization using UV-Vis, ES-TOF, MALDI-TOF, and one-dimensional and two-dimensional NMR spectroscopy. Moreover, the sulfanyl porphyrazine was subjected to various photophysical studies, including optical absorption and emission measurements, as well as the evaluation of its photochemical properties. Values of singlet oxygen generation quantum yields were obtained in different organic solvents. The electrochemical properties of the synthesized compounds were studied using cyclic voltammetry. According to the electrochemical results, the presence of electron-withdrawing oxohexyl groups attached to ferrocene afforded significantly more positive oxidation potentials of the ferrocene-based redox process up to 0.34 V vs. Fc+/Fc.

The Problem of CO2 Reabsorption in Emission Spectra

The authors present a detailed explanation for selective reabsorption by the CO2 ν3-band when passing its optical emission through an atmospheric-pressure air column (60 cm long, 410 ppm CO2) connecting a microwave-discharge cell and the entrance window of a high-resolution Fourier Transform spectrometer. The CO2 band shapes are explained with a two-temperature model of emission and foreground absorption. Selective CO2 atmospheric reabsorption is a common effect in optical emission measurements. It primarily affects the fundamental infrared bands, which comprise the main part of the missing laboratory emission and must be taken into account in (exo)planetary atmospheric models.

Emission thermometry of microwave-assisted alkali-doped propellant combustion

Recently, the application of high-power microwave fields to sodium-doped aluminized solid propellants has been shown to increase the atmospheric burning rate by up to 60%. Two main mechanisms have been proposed to increase the burning rate: (1) plasma enhancement by the presence of low-ionization threshold sodium and (2) the dielectric thermal runaway heating of metallic-oxide products. To examine the mechanisms of microwave energy deposition in the solid propellant burning strands, optical emission measurements were made during the application of a 2.46 GHz, 870 W microwave field in a single-mode microwave resonator. Flame temperature measurements are made via gas-phase AlO B2Σ+→X2Σ+(Δv=−1) electronic emission spectroscopy, spatially-resolved two-color imaging pyrometry of the condensed phase, and spatially-resolved two-line sodium emission thermometry. These experiments indicate an increase in the gas phase AlO temperature of ∼130 K, and a ∼1200 K increase in the sodium gas-phase temperature during the application of the microwave field. Gray body condensed-phase temperatures of burning aluminum particles indicated little temperature change, but the product plume temperature increased by ∼700 K. These temperature measurements of the vapor and condensed phase products indicate several important pathways for the thermalization of the field energy throughout the propellant flame structure, offering opportunities for further optimization of electromagnetically tunable energetic material combustion.

Color tunable photoluminescence in KZABS: Tm3+ glasses under different sources of excitation for photonic applications

Potassium Zinc Alumino Borosilicate (KZABS) glasses doped with Tm3+ ions have been prepared by using a melt quenching process and further investigated through various spectroscopic tools such as optical absorption, photoluminescence (PL) excitation, PL emission, and PL decay measurements. The non-crystalline nature of the as-prepared glasses was confirmed by XRD measurements. PL spectral properties show blue and red colors under different excitation wavelengths. The absorption spectrum recorded in the UV-Vis-NIR range reveals the high bandgap energy. The Inokuti-Hirayama (I-H) model well fitted to non-exponential decay curves confirms the energy transfer between Tm3+-Tm3+ ions as dipole-dipole in nature. Under 359 and 466 nm excitation wavelength the titled glasses are showing CIE coordinates falling in deep blue and deep red color, respectively. A good color tunability can be seen from the blue to the red region under different excitation wavelengths. All the studies finally reveal the superiority of Tm3+ doped KZABS glasses for their usage in blue/red-emitting photonic devices needed to fabricate photonic devices such as w-LEDs.

Transient optical absorption in calcium fluoride crystals

We report time-resolved measurements of transient optical absorption and emission in nominally pure CaF2 crystal. For excitation we used a pulse of accelerated electrons. It was shown that irradiation leads to the formation of centers of induced absorption, which are deconvoluted by the set of Gaussian bands with maxima at 2.70, 2.91, 3.09, 3.30 eV (F centers) and 3.825, 4.03, 4.30, 4.83 eV (H centers). Four possible geometries of the STE in the fluorite lattice are shown. Assumptions are made about the conversion of configurations.

Effects of oxidizer structure on thermal and combustion behavior of Fe2O3/Zr thermite

Performance of MOF-derived micrometer porous Fe2O3 as the oxidizer in Zr-fuelled thermite is compared with commercial nano-sized Fe2O3 by characterizing thermal and combustion behavior of Fe2O3/Zr mixture via differential scanning calorimetry, optical emission measurement as well as composition and morphology analysis on condensed combustion products. Results show that thermal behaviors of Fe2O3/Zr with a slow heating rate have little difference regardless of the kind of Fe2O3. However, MOF-derived micrometer porous Fe2O3 show an obvious superiority in enhancing combustion of Fe2O3/Zr heated by a high rate. Combustion reactions of Fe2O3/Zr under high heating rates are probably rate-controlled by condensed reaction. The better performance of MOF-derived Fe2O3 is attributed to its larger contact area with Zr particle in that micrometer porous Fe2O3 particles are easily broken into primitive nano-sized particles, which effectively avoid the agglomeration of oxidizer. The MOF-derived Fe2O3 particles obtained at calcination temperature of 550 °C enable the best combustion performance of Fe2O3/Zr thermite. This should be because the crystallinity and porous structure of 550 °C-Fe2O3 are more favorable for the mass transfer process during high-rate combustion.

Finally, the potential of the presented diagnostics to solve future challenges of thermal arc research is demonstrated and discussed.

Radial spatiotemporal evolution of rf magnetic field and plasma current in a very-high-frequency plasma source over a wide range of plasma density and pressure.

We present detailed spatiotemporal measurements of rf magnetic fields and plasma conduction current as well as the corresponding plasma density profiles when very-high-frequency 100-MHz waves are introduced to a parallel plate plasma. The magnetic probe, optical emission, and plasma absorption probe measurements support a model in which the interaction of high-frequency waves with the moving plasma sheath at specific phases of the very high frequencies (VHF) period leads to local reversals in the vertical rf electric field which can lead to conduction current reversals and circulations. The presence of current reversals and circulation correlate with measured plasma uniformity. In particular, measured electric field and current reversals coincide with the strongly center-peaked plasma density profiles frequently observed in VHF plasma. The magnitude of the center peak increases with the number and magnitude of the current reversal cells. The scale length of the current reversal cells is on the order of what is expected for plasma surface waves. Measurements indicate that plasma conductivity is the common scaling factor for both plasma uniformity and the circulation. The propagation of high-frequency waves and the generation of rf current reversal in one phase of the rf cycle rather than another results in the appearance of harmonics in Fourier decomposed magnetic probe wave forms. These harmonics turn out not to be actual waves or evidence of standing waves at these frequencies but rather consequences of packets of wave propagation that occur periodically.

Synthesis, optical and thermoluminescence properties of thulium-doped KMgF3 fluoroperovskite

KMgF3 fluoroperovskite doped with thulium at different concentrations were synthesized by the solid-state reaction method. The phase composition and the thermal stability up to 600 °C of the polycrystals were analyzed by X-ray diffraction and thermogravimetric analysis, respectively. The KMgF3 at 1.0 mol% of Tm polycrystals showed the best thermal stability and did not present another phase. The gamma radiation (0.1–10 kGy) effect in thulium-doped KMgF3 produced the F color centers, and their aggregates such as F2, and F3 centers. The F centers, and the potassium vacancies (VK−) in the fluoroperosvkites were analyzed by the optical absorption and emission measurements. Optical absorption at 275 nm and 443 nm were assigned to F and F2, respectively, in undoped KMgF3. Tm-doped fluoroperovskite shows the optical absorption bands at 277, 393, 432, and 577 nm, which were ascribed to the F, F3, F2 and VK− centers, respectively. When the F band for undoped polycrystals was excited at 275 nm, a clear emission associated with F2 and F3 centers was observed. In the case of Tm-doped, an enhancement of the blue emission at 457 nm occurred and a UV band (354 nm) was observed upon exciting the F band. The blue emission of thulium was overlapped with the F3 color center band. The emission bands at 457 and 354 nm were ascribed to 1D2 - 3F4 and 1D2 - 3H6 transitions of Tm in KMgF3. The optical absorption and glow curves were investigated too. The glow curves were assisted by the color centers, vacancies, and thulium impurity. Thermal bleaching shows that the F center was the main participant to give rise to the TL intensity of the glow curves. Thulium acts as a deep electron trap in the bandgap of the KMgF3 fluoroperovskites forming TL peak at the higher temperature, from 430 to 408 °C. The absorption, emission, and thermoluminescence glow peaks of the undoped and Tm-doped KMgF3 were compared.

Electron temperature measurements with a hairpin resonator probe in a pulsed low pressure capacitively coupled plasma

Electron temperature is measured from time resolved hairpin resonator probe measurements in a pulsed capacitively coupled argon plasma at 400 mTorr. Effective collision frequency is related to the electron energy distribution via the effective conductivity and closes a system of equations that allow electron temperature to be determined. Results generally show good agreement with expected behavior and unfiltered time-resolved optical emission measurements.

Energy transfer analysis and realization of cool to warm white light in Dy3+ /Sm3+ /Er3+ triply doped multicomponent borosilicate glass for white light generation.

A series of Dy3+ /Sm3+ /Er3+ triply doped multicomponent borosilicate glasses (DSE) was synthesized using varying Er3+ ions concentrations through a conventional melt quenching technique. The influence of triple doping on the optical characteristics of the prepared glass was evaluated to estimate the possibility of achieving white light emission through optical absorption, photoluminescence excitation (PLE), and emission (PL) measurements. Based on the PLE and PL spectral profiles, the presence of energy transfer processes between Dy3+ , Sm3+ , and Er3+ was confirmed. Furthermore, for Dy3+ /Sm3+ /Er3+ triply doped glass, an enhancement in Er3+ green luminescence and a noticeable decrease in Dy3+ and Sm3+ emissions were detected with the increase in Er3+ concentration. The nature of energy transfer in DSE glass was investigated through Dexter's energy transfer mechanisms and the obtained result suggested that a dipole-dipole interaction was responsible for the dominant Sm3+ to Dy3+ and Dy3+ to Er3+ energy transfer processes. The precise characteristic colours that emanated from the as-prepared samples were evaluated using Commission Internationale de l'Éclairage co-ordinates and correlated colour temperature values and suggested its suitability for white light emission. The quantum efficiency of the prepared glass was determined experimentally. The aforementioned results recommend that the Dy3+ /Sm3+ /Er3+ triply doped multicomponent borosilicate glass irradiated with ultraviolet light sources might be useful for the generation of cool/warm white light-emitting applications.

Effects of direct current bias on nucleation density of superhard boron-rich boron carbide films made by microwave plasma chemical vapor deposition

We report bias enhanced nucleation and growth of boron-rich deposits through systematic study of the effect of a negative direct current substrate bias during microwave plasma chemical vapor deposition. The current flowing through a silicon substrate with an applied bias of −250 V was investigated for a feedgas containing fixed hydrogen (H2) flow rate but with varying argon (Ar) flow rates for 1330, 2670, and 4000 Pa chamber pressure. For 1330 and 2670 Pa, the bias current goes through a maximum with increasing Ar flow rate. This maximum current also corresponds to a peak in substrate temperature. However, at 4000 Pa, no maximum in bias current or substrate temperature is observed for the range of argon flow rates tested. Using these results, substrate bias pre-treatment experiments were performed at 1330 Pa in an Ar/H2 plasma, yielding the maximum bias current. Nucleation density of boron deposits were measured after subsequent exposure to B2H6 in H2 plasma and found to be a factor of 200 times higher than when no bias and no Ar was used. Experiments were repeated at 2670 and 4000 Pa (fixed bias voltage and Ar flow rate) in order to test the effect of chamber pressure on the nucleation density. Compared to 4000 Pa, we find nearly 7 times higher boron nucleation densities for both 1330 and 2670 Pa when the substrate was negatively biased in the Ar/H2 plasma. Results are explained by incorporating measurements of plasma optical emission and by use of heterogeneous nucleation theory. The optimal conditions at 1330 Pa for nucleation were used to grow boron-rich amorphous films with measured hardness as high as 58 GPa, well above the 40 GPa threshold for superhardness.

Down-conversion luminescence and shielding parameters of Dy3+: NFBT glass for white LED and radiation applications

A new kind of dysprosium (Dy3+) ions doped niobium fluoro borotellurite (NFBT) glass with compositions (35- x )TeO2 + 30H3 BO3 + 15Nb2O5 + 10SrCO3 + 10CdF2 + x Dy 2O3 (where x = 0.05, 0.3, 0.5, 1, 2 and 3 in wt. %, hereafter refers as to Dy 3+ ions’ concentration) was fabricated with melt quenching method and characterized through X-ray diffraction, physical (density (ρ), molar volume of oxygen (V o), and optical basicity ( th), etc.), visible absorption, excitation, emission and lifetime measurements. Its density increases while its molar volume decreases with increase of Dy3+ ions, which indicates that the glass becomes more compact. The absorption spectrum shows the various characteristic peaks of Dy3+ ions attributed to the transitions from the 6H 15/2 ground level to the different excited energy levels. The oscillator strengths and Judd-Ofelt intensity parameters (W l =2, 4 & 6) were articulated from the optical absorption spectrum. The photoluminescence spectrum reveals that this NFBT glass has several emission bands, corresponding to 4F 9/2 → 6H 15/2 (blue), 4F 9/2 → 6H 13/2 (yellow) and 4F 9/2 → 6H 11/2 (red) transitions, respectively. The emission intensity increased with Dy3+ ions concentration from 0.05 wt. % to 1 wt. %, after that the concentration quenching was observed for higher concentrations (2 & 3 wt. %). The non-exponential decay curves were analysed with Inokuti-Hirayama (IH) model ( S =6), indicating a nature of dipoledipole interaction between the donor and the acceptor of Dy3+ ions. The Commission International de’Eclairage (CIE 1931 (x , y) and CIE 1976 ( u , v )) coordinates and the correlated color temperature (CCT) values clearly show that the present glass can be useful in cool white light (CCT>4000 K) region. Moreover, mass attenuation coefficient (μ / ρ), and effective atomic number (Z eff) parameters were also articulated through Phy-X/PSD program. Hence, the results indicate that the prepared glasses could be suitable for laser, smart white LED (1DyNFBT) and gamma ray shielding (3DyNFBT) applications. • A novel series of Dy 3+ : NFBT glasses were prepared with melt quenching. • Luminescence and colorimetric parameters (CIE, CP , CCT, Y/B ratio) were evaluated. • Gamma radiation shielding parameters (MAC, HVL, MFP, Ʃ R , Z eff , etc.) were analysed. • 1DyNFBT and 3DyNFBT glasses can be suggested for WLED and gamma ray shielding applications.

Discrimination of pistachio cultivars based on multi-elemental fingerprinting by pattern recognition methods

The potential of multi-elemental fingerprinting based on inductively coupled plasma optical emission measurements (ICP OES) was examined to classify pistachio cultivars. Five pistachio cultivar samples were collected during the harvesting period 2017–2018 from Kerman in Iran. The ability of multivariate data analysis approaches, such as principal component analysis (PCA) and principal component analysis-linear discriminant analysis (PCA-LDA) have been investigated in order to achieve discrimination of different cultivars. Eighteen variables i.e. the contents of Al, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, Pb, Sr and Zn at mg g−1 level, determined by ICP OES were used. The results showed that the five pistachio cultivars can be identified based on the multi-elemental fingerprints. The loading plot of PCA illustrated that Pb, Cr, Co, Cd, and Ba have the lowest contributions in discrimination of the different pistachio cultivars. Almost all samples were correctly classified by the PCA-LDA model using cross validation (99.0%). The mean sensitivity and specificity were 98.0% and 99.6%, respectively, indicating the satisfactory performance of the model. The results demonstrate multi-elemental fingerprinting combined with multivariate data analysis methods can be employed as an effective and feasible method for classification of Iranian pistachio based on their cultivars.

Straightforward synthesis of silicon vacancy (SiV) center-containing single-digit nanometer nanodiamonds via detonation process

Silicon vacancy (SiV) color centers in diamond have attracted widespread attention owing to their stable photoluminescence (PL) with a sharp emission band in the near-infrared region (ZPL 738 nm). Especially, SiV center containing single-digit nanometer-sized nanodiamonds (single-digit SiV-NDs) are desirable for various applications such as bioimaging and biosensing because of their extremely small size, comparable to many biomaterials. Therefore, several attempts have been made to fabricate the single-digit SiV-NDs. However, there are no reports on the successful fabrication of such materials in reasonable scale of production. Here, we report the successful synthesis of single-digit SiV-NDs via straightforward detonation process, which is known to have the high productivity in fabrication of single-digit NDs. Triphenylsilanol (TPS), as a silicon source, was mixed with explosives (TPS/TNT/RDX = 1/59/40 wt%) and the detonation process was carried out. The obtained single-digit NDs exhibit PL at approximately 738 nm, indicating that single-digit SiV-NDs were successfully synthesized. Moreover, we conjectured that the physics behind this achievement may be attributed to the aromatic ring of TPS under the consideration of ND formation mechanism newly built up based on the results of time-resolved optical emission measurements for the detonation reaction.

Linear Optical Absorption, Emission Properties and Ultrafast Carrier Dynamics of Aqua‐chloro‐bis(1,10‐phenanthroline)manganese(II) 4‐formylbenzoate Trihydrate

AbstractIn this study, the synthesis, Hirshfield surface analysis, linear absorption, fluorescence properties and carrier dynamics of [Mn(1,10‐phenanthroline)2(H2O)Cl].(4‐formylbenzoate)(H2O)3 complex were reported. To determine of the structure the complex, elemental analysis, FT‐IR Spectra, and single crystal X‐ray diffraction analysis were done. The linear optical absorption and emission measurements of the complex in DMSO solvent at 0.5 g/L concentration were recorded by UV‐Vis and fluorescence spectrophotometers, respectively. The carrier dynamics of the complex was obtained by using time‐resolved transmission pump‐probe spectroscopy. In the light of the obtained optical results, it can be said that the complex is linear optically ultraviolet absorber, nonlinear optically excited state absorber and wide range emitter with fast response time. The intermolecular interactions which are occurred in the complex were investigated by Hirshfeld surface analysis. Three dimensional dnorm and two dimensional fingerprints plots of the complex were obtained from Hirshfeld surface analysis. In this way, the amounts of the chemical bounds, taking place in the structure were determined and used to support of the discussion of the linear optical absorption and emission results which were experimentally obtained.
