1.06 µm emission of Nd3+-doped aluminium barium lithium phosphate glasses for near IR laser medium material

Melt quenching was used to make aluminum barium lithium phosphate glasses doped with various amounts of Nd3+ ions. The absorption spectra of glasses showed twelve peaks and were increased with increasing of Nd2O3 concentrations. While the wavelength at 581 nm is the highest absorption. The emission spectra of Nd3+-doped glasses exhibited three dominant peaks at 901, 1066 and 1334 nm under exciting wavelength at 581 nm, it was related to the 4F3/2→4I9/2, 4I11/2 and 4I13/2 transitions, respectively. The wavelength at 1066 nm was observed that is the highest emission intensity. Because of the concentration quenching effect, the emission intensities accreted regarding concentration up to 1.0 mol%. After that, when it was higher than 1 mol%, the intensity decreased. The Ω2,Ω4andΩ6 were done by applying Judd-Ofelt theory to the absorption and emission results, which led to the calculation of the radiative transition probability and the stimulated emission cross-section. The JO parameters show Ω6>Ω2>Ω4 trend, it indicated more viscosity and rigidity of glasses. Glasses have had their stimulated emission cross-section determined. The results showed that Nd3+-doped aluminium barium lithium phosphate glass with a 1066 nm emission might be used as a near-infrared laser medium material.

OPTIMIZED RELATIVISTIC MANY-BODY PERTURBATION THEORY IN CALCULATIONS OF ATOMIC SPECTRAL AND RADIATION CHARACTERISTICS: Eu ATOM

The new formalism of the relativistic gauge-invariant perturbation theory (RMBPT-ODF) with the optimized Dirac-Fock approximation and a generalized energy approach is applied to the study of energy, radiation, and spectroscopic characteristics of a group of heavy atomic systems, in particular, energy levels and transition probabilities and oscillator strengths of the transitions 4f7(8S)6s2 8S7/2 4f7(8S)6s6p 8P5/2,7.2,9.2, 4f7(8S)6s7p 8P5/2,7\2, 4f7(8S)6s8p 8P9/2,7\2 in spectrum of the europium atom Eu I. It is shown that the required formalism, in comparison with the standard non-optimized relativistic Hartree-Fock and Dirac-Fock methods, allows obtaining more accurate data both on energies and amplitudes and probabilities of radiative transitions, which is due to the use of the optimized zero ODF approximation, a fairly complete and effective account of complex many-body exchange-correlation effects. The contribution due to the polarization of the core reaches 30% of the value of the oscillator strength; the value of the calibration-invariant contribution to the radiation width is fractions of a percent, in contrast to all existing methods of modern atomic spectroscopy, for which the contribution reaches 5-50%.

Influence of excitation nature on temperature attenuation of luminescence in ZnSe crystals

Experimental studies have shown that temperature attenuation of luminescence in undoped ZnSe crystals depends on the nature of the band-band excitation. It is determined that this attenuation differs from the attenuation at intracentric excitation of the 630 nm luminescence band.A comparative analysis of the results of the action of X-rays, N2 laser (337 nm) and LED-390 (390 nm) shows that the temperature dependence of luminescence depends on the density of generated free electron-hole pairs.The corresponding theoretical dependences for external luminescence attenuation and in the presence of simultaneous intracentric and external luminescence attenuation are obtained. Analysis of the shape of the curves of temperature luminescence attenuation shows that the increase in the excitation density increases the probability of radiative transitions from the excited state of the luminescence center in comparison with nonradiative transitions. This is confirmed by the lux-luminescent characteristics of X-ray and photoluminescence at different temperatures. It can be stated with high probability that the temperature position of the beginning of the temperature attenuation of luminescence is affected by forced transitions in the scintillation pulse.

Optical, luminescence, and energy transfer studies of Gd3+/Dy3+ doped potassium gadolinium borophosphate glasses

The K2O–Gd2O3–B2O3–P2O5 glass doped with Dy2O3 (Dy:KGPB) were synthesized by the melt-quenching technique. These glasses were subjected to characterize the physical, structure, optical and luminescence properties. It was observed that the density, molar volume and refractive index of glass increased with increasing Dy2O3 concentration. The FTIR result confirmed the main glass network of BOB and POP linkages those were degraded by adding Dy2O3 modifier. Glasses absorbed photons in ultraviolet, visible light and near-infrared region. The photoluminescence under direct Dy3+ excitation performed the strong emissions at 574 and 482 nm corresponding to 4F9/2 → 6H13/2 and 4F9/2 → 6H15/2 transition, respectively. The Gd3+ excitation also caused strong emission of Dy3+ by the Gd3+-Dy3+energy transfer. Glass doped with 1.00 mol% of Dy2O3 owned the highest emission intensity due to the concentration quenching. The lifetime of 4F9/2 level was found to decrease with addition of Dy2O3 content via dipole-diploe interaction between Dy3+ ion. Judd-Ofelt (J-O) intensity parameters were initially calculated and applied to evaluate the radiative parameters such as branching ratios, radiative transition probabilities, and stimulated emission cross-sections. The radioluminescence of glass was also investigated and found the scintillation efficiency around 15.6%, compared to BGO scintillator. The Dy:KGPB glass has an interesting potential for solid-state laser, LED and X-ray detection applications.

Thermal and fluorescence properties of Nd2O3-doped Gd2O3-Ga2O3-GeO2 glass based on the Judd-Ofelt theory

A novel type of xNd2O3-doped 14.75Gd2O3-23.33Ga2O3-(61.92-x)GeO2 glasses were successfully prepared. The thermal stability of the glass was studied by DSC and the forming ability of the glass was analyzed by XRD. Based on Judd-Ofelt theory, the strength parameters (Ω = 2, 4, 6) and radiation characteristics of the glass were analyzed detailedly by absorption and emission spectra. The results show that when the doping Nd2O3 is 1 mol%, the glasses not only have more stable thermal properties, but also have the best emission spectral intensity at 4F3/2→4I11/2 (1060 nm) with excellent radiative transition probability and stimulated emission cross section (σemis). Furthermore, it is found that the luminescence intensity of the glass ceramics obtained after heat treatment was increased by about 4.5 times due to the formation of GdGaGe2O7 crystal phase. In conclusion, the novel Nd2O3-doped Gd2O3-Ga2O3-GeO2 glass has the potential as a high power laser (1.06 μm) application material.

Eu3+ ions doped lithium aluminium gadolinium borophosphate glasses: Energy transfer, optical and luminescence behaviors for red emission material

Eu3+ ions doped Li2O–Al2O3–Gd2O3–B2O3–P2O5 glasses have been prepared by melt quenching and characterized for their physical, optical and luminescence properties. Judd-Ofelt (JO) theory is used to evaluate the oscillator strengths and the three intensity parameters (Ωλ, λ = 2, 4 and 6) of the glasses. The radiative properties such as radiative transition probabilities (AR), radiative lifetimes (τ), branching ratios (β) and emission cross-section (σe) have been calculated from the absorption spectra according to the JO theory. The scintillation properties of glasses could be measured by comparing emission spectrum under the X-ray induced luminescence with bismuth germanate (BGO). The Commission Internationale de l’Elcairage (CIE) chromaticity coordinates (x,y) were also evaluated from the emission spectra of glasses and values of glasses take part in the red region.

Influence of external magnetic field on the electronic structures and radiative properties in plasma-embedded multi-electron atomic systems

A method within the fully relativistic frame, based on the reconstructed Dirac–Coulomb Hamiltonian is suggested which applies to the plasma-embedded multi-electron atomic systems perturbed by applied magnetic fields. The proposal is a configuration interaction method and based upon a combination of two concepts, referred to as plasma screening and external magnetic field. An effective potential, derived by introducing a parameter dependent scaling of the radial dependence of free electron contribution in the ion-sphere, is adopted to model the interactions among the charged particles in dense plasmas, and also the range of external weak magnetic field B<105 T is considered. In this instance, numerical calculations are performed for electronic structures and spectroscopic properties of the He atom and Fe14＋ ion as examples. The accuracy of the present approach is shown by comparison to previous theoretical calculations. The behavior of energies of low excited states and radiative transition probabilities for allowed transitions as a function of the plasma screening and field strength is classified. These results are developed in high energy density physics and astrophysics context.

Band-Edge Effect-Induced Electrochemiluminescence Signal Amplification Based on Inverse Opal Photonic Crystals for Ultrasensitive Detection of Carcinoembryonic Antigen.

Photonic crystals (PCs) have emerged as a promising electrochemiluminescence (ECL) matrix in the domain of immunoassay. Making maximum use of light manipulation properties of PCs is highly desired for improving the sensitivity. In this work, we proposed a band-edge effect-induced ECL enhancement strategy based on silica inverse opal PCs (SIOPCs). By fine-tuning the lattice constant and carefully calibrating the stopband position, we found that the band edge of the stopband exerted significant influences on the ECL intensity and spectral distribution. The high density of states at the blue edge of the photonic band gap increased the radiative transition probability of ECL emitters and enhanced the photon extraction during propagation, giving rise to ∼20-fold ECL signal amplification accompanied by a redistributed ECL spectrum for the Ru(bpy)32+-TPrA system. In combination with the intrinsic structural superiority, like large specific surface area and interconnected macropores, the developed SIOPC electrode was successfully applied in constructing a sandwich-type immunosensor. The fabricated immunosensor displayed a very low detection limit of 0.032 pg/mL and a wide linear range of 0.1 pg/mL-150 ng/mL for a carcinoembryonic antigen assay, showing its potential application in disease diagnosis.

Crystal growth and luminescence characterization of LaCl3:Dy3+ single crystal for the laser application

This paper reports the LaCl3:Dy3+ single crystal that was successfully grown by an in-house-developed Bridgman furnace. Powder X-ray diffraction (XRD) data were investigated for structural characterization of LaCl3:Dy3+ single crystal. The emission spectrum of the grown crystal was recorded under UV excitation, which reveals intense emissions in the blue (478 nm) and yellow (571 nm) regions, corresponding to the characteristic Dy3+ transitions. The CIE coordinates and CCT values were used to determine the color of the emitted light, obtained from the emission spectra. Judd-Ofelt theory was also applied to calculate the JO parameters (Ω2, Ω4, and Ω6) and radiative properties such as radiative transition probabilities (AR), stimulated emission cross-sections (σ(λp)), and branching ratios (βR). The results illustrate the capability of the LaCl3:Dy3+ crystal, a promising candidate for a 571 nm laser source.

The influence of Er3+ ions on the spectroscopic and lasing characteristics of alkaline earth titanium borate glasses for photonic applications

Alkaline earth titanium borate glasses doped with different ratios of Er3+ ions were fabricated using standard melt quenching technique. The density of the glasses increased from 3.652 to 3.762 g/cm3 as the ratio of Er3+ ions increased from 0 to 5.640 × 1020 cm−3. The gaussian deconvolution of the Raman and FTIR spectra was investigated, and the distinctive spectral vibrational bands were assigned. The UV–Vis–NIR absorption spectra of the erbium doped glasses exhibit nine bands located at 1531, 980, 808, 654, 520, 490, 446, 408, and 377 nm due to the electronic transitions of Er3+ ions from the ground level 4I15/2 to the higher excited levels 4I13/2, 4I11/2, 4I9/2, 4F9/2, 2H11/2, 4F7/2, 4F3/2, 2G9/2, and 4G11/2, respectively. The structural and luminescent properties of the erbium doped glasses were investigated by calculating Judd – Ofelt intensity parameters, radiative transition probabilities, branching ratio, lifetime, full width at half maximum (FWHM), and gain bandwidth (FWHM × σemis). The intensity parameters followed the trend as Ω2> Ω6> Ω4 for all glasses. The values of Ω2 decreased from 5.2079 × 10−20 to 3.8133 × 10−20 cm2 and that of Ω4 decreased from 0.7402 × 10−20 to 0.5939 × 10−20 cm2 as the ratio of Er3+ ions increased. The high laser efficiency of the studied glasses were verified by the high values of the radiative lifetime, branching ratio, FWHM, and gain bandwidth. The gain spectra for BaTiBEr3 and BaTiBEr5 glasses covered the conventional (1530–1565 nm) and long (1565–1625 nm) communication bands. Moreover, the high values of the FWHM and gain bandwidth for BaTiBEr3 and BaTiBEr5 glasses, suggested their suitability for photonic applications in the near infrared region and broadband optical fiber amplifiers.

Structural and luminescence characteristics of thermally stable Dy3+ doped oxyfluoride strontium zinc borosilicate glasses for photonic device applications

Structural, thermal, and photoluminescence (PL) characteristics of a series of Dy3+ doped Oxyfluoride Strontium Zinc Borosilicate (OFSZBS) glasses have been investigated. The XRD of 1.0 mol% Dy3+ ions doped OFSZBS glass and FT-IR investigations conducted on an un-doped as well as all the Dy3+ ions doped OFSZBS glasses confirm the non-crystalline nature and distinct functional groups present in it respectively. The Differential Scanning Calorimetry (DSC) thermogram recorded for an un-doped OFSZBS glass reveals thermal stability (ΔT) and transition temperature (Tg). The optical band gaps were computed using the Tau'c method. Under 348 nm pumping wavelengths, the Photoluminescence (PL) spectra of the as-synthesized OFSZBSDy glass samples exhibit blue (450 nm), yellow (575 nm), and red (650 nm) color transitions. The PL intensity increases with Dy3+ ions concentration up to 1 mol% and after that intensity decreases due to the concentration quenching effect. The PL decay profiles reported at higher concentrations were best fitted to the Inokuti-Hirayama (I-H) model for s = 6, indicating the energy transfer process as dipole–dipole in nature. The result obtained from the I-H model is in consonance with that of Dexter's theory. At 448 K, the PL intensity is up to 85% of room temperature, indicating that the as-synthesized glasses have exceptional thermal stability. Relatively higher values of quantum efficiency (η), emission cross-sectional area (σse), and probability of radiative transition (AR) observed for 1 mol% Dy3+ ions doped OFSZBS glasses declare their suitability in photonic devices under n-UV/blue pumping wavelength.

NIR photoluminescent characteristics of Nd3+ activated fluoroborosilicate glasses for laser material applications

Spectroscopic investigation on the optical characteristics of 1.06 μm (4F3/2 → 4I11/2) transition of Nd3+ ions with different concentration in fluoroborosilicate (FBSND) glasses is reported. The glass transition temperature estimated via DSC analysis confirmed the thermal stability of the Nd3+ doped fluoroborosilicate glassy system. The phenomenological Judd-Ofelt parameters were evaluated by implementing the Judd–Ofelt (JO) theory on the recorded absorption spectrum and the parameters. Strong NIR emission has been observed for the lasing transition at 1.06 μm under an excitation of 584 nm. The emission intensity of all the luminescent bands in the NIR emission spectra of FBSND glasses observed to be increased up to 1 mol% and after that a fall in emission intensity is observed due to concentration quenching. Large value of JO intensity parameters and radiative properties such as branching ratio, stimulated emission cross section, radiative transition probability recommends FBSND glasses for photonic applications.

Sm3+ ions doped Sm2Si2O7-based glass ceramics: Crystallization, luminescence and energy transfer process through heat treatment

Sm3+ ions incorporated Sm2Si2O7 crystalline phase formed in the aluminoborosilicate glass matrix synthesized via melting quenching technique followed by heat-treatment process is reported herewith. The preliminary confirmation on the obtained glass ceramics was made through X-ray diffration (XRD) studies. Formation of non-bridging oxygens (NBOs) in the glass network and the modes of vibrations of network units were analyzed through Fourier transform infrared spectroscopy (FTIR) studies. Surface morphology of heat-treated samples at varying temperatures was determined via a field emission scanning electron microscope (FESEM). The absorption studies on heat-treated samples signify the low bandgap values and high Urbach energy values due to improved crystallinity in the glass network. Judd–Ofelt intensity parameters identified for visible absorption transitions follow the trend of Ω4 >Ω2>Ω6. Excitation and emission studies on heat-treated samples show improvement in their intensities compared to the unheated base glass. The thermal quenching is observed at higher temperatures (540 and 580 °C for 3 h) of heat-treated samples. Calculations based on luminescence spectra including radiative transition probability, stimulated emission cross-section and branching ratio show good results for glass ceramics prior to precursor glass. Longer lifetimes of Sm3+ ions (milliseconds) in the level 4G5/2 are seen for glass ceramics. Color coordinates suggest the reddish-orange emissions from prepared glass ceramics. Thus, Sm3+ doped Sm2Si2O7 glass ceramics are favorable materials for solid-state lighting and laser applications.

The growth process parameters have been investigated in detail. X-ray diffraction (XRD) and Raman spectroscopy measurements showed that the K+ and Na+ cations occupied equivalent lattice sites and the crystal structure remained monoclinic. The spectral properties and energy transfer mechanisms of the single crystals doped with different concentrations of Er3+ ions were investigated. According to the Judd-Ofelt theory, the intensity parameters of the 5 mol% Er: NKYW crystal were calculated to be Ω2 = 1.77 × 10−20 cm2, Ω4 = 3.15 × 10−20 cm2, Ω6 = 3.08 × 10−20 cm2, and the radiative transition probability of 4I13/2 → 4I15/2 was 541.25 s−1. The gain cross section of the 5 mol% Er: NKYW crystal at 1542 nm was determined to be 2.63 × 10−20 cm2, indicating that high-quality Er: NKYW single crystals have great potential for laser applications.

Investigation of Eu3+ Doped Oxy-Fluoride Phosphate Glass for Red Laser Gain Medium Application

The oxyfluoride phosphate glass doped with europium oxide was synthesized by melt quenching technique. The structural and spectroscopic analysis has been carried out by Raman, absorption, photoluminescence, phonon side band and lifetime analysis. The absorption spectrum revealed the characteristic transitions between the 7F0 ground state and 7F1 first excited state to the upper-lying electronic states. The several J-O parameters: oscillator strength, radiative transition probability, stimulated emission cross-section and branching ratio. The local structure around the Eu3+ ions and the phonon energy of oxyfluoride phosphate glass have been confirmed on the basis of PSB associated with the 7F0→5D2 transition. The highest excitation spectrum showed at 395 nm for transition 7F0→5L6. The emission spectrum showed two major peaks corresponding to 591 nm orang emission (5D0→7F1) and 613 nm red emission (5D0→7F2). This work confirmed that 1 mol% Eu2O3 doped oxyfluoride phosphate glass performs a high potential for using as efficient luminescence materials for solid-state lighting application, especially for reddish-orange light-emitting glass.

Spectroscopic and optical investigations on Er3+ ions doped alkali cadmium phosphate glasses for laser applications

Alkali cadmium phosphate glasses doped with erbium ions were prepared by traditional melt - quenching technique. The FTIR and Raman spectroscopies were performed and employed to investigate the structural changes of the glass network doped with different concentrations of Er3+ ions. The UV–Vis–NIR spectroscopy was used to investigate the optical absorption spectra, optical bandgaps, refractive indices, and related parameters. The Judd – Ofelt (J – O) theory was used to explain the structural changes and to determine the bonds nature in the studied glasses by calculating the intensity parameters Ω2, Ω4, and Ω6. The J – O intensity parameters followed the trend of Ω2 > Ω6 > Ω4 and were used to evaluate some radiative parameters such as electric and magnetic radiative transition probabilities, branching ratios, and radiative lifetimes for the excited levels of the Er3+ ions. The absorption and emission cross-sections for the 4I13/2 → 4I15/2 transition of Er3+ ions were studied, and the gain coefficient was calculated. The higher values of the branching ratios (≥ 0.5) and lifetimes of the present glasses indicate their good suitability for lasers and amplifiers applications.

Structural, thermal, optical and luminescence properties of Dy3+ ions doped Zinc Potassium Alumino Borate glasses for optoelectronics applications

Zinc Potassium Alumino Borate (ZnKAlB) glasses doped with dysprosium (Dy3+) ions of different concentrations were synthesized through the process of melt quenching which is commonly used in solid-state lighting (SSL) and laser systems, to comprehend their viability. This article evaluates and analyzes the physical, structural, thermal and optical properties of Dy3+ ions doped glasses by X-ray diffraction (XRD), Infrared Fourier Transform (FT-IR), differential scanning calorimetry (DSC), UV absorption and photoluminescence (PL) spectra to explain their utilization in optoelectronic devices such as lasers and white light-emitting diodes (w-LEDs). The physical parameters viz. density, refractive index, inter-ionic distance, molar volume, polaron radius, field strength, optical electronegativity, dielectric constant, reflection loss and metallization were computed by following the expressions reported in the literature. Glasses are non-crystalline materials and the non-crystallinity of an un-doped Zinc Potassium Alumino Borate glass was proven by the absence of high-pitched peaks in the XRD spectra. FT-IR spectroscopy was used to identify the presence of different functional groups and their bond nature in Dy3+ ions doped ZnKAlB glasses. The transition temperature (Tg), melting temperature (Tm) and thermal stability was calculated by monitoring DSC thermograms of all glasses. Further, the bonding parameters (δ) and nephelauxetic ratio (β) were estimated to explore the bonding nature of Dy3+ ions in its neighborhoods by using UV-absorption data. The optical direct-indirect band gap energy (Eopt) and Urbach's energy (∆E) were enumerated from the absorption spectrum to elaborate electrical properties of as-prepared glasses. Judd-Ofelt theory was employed to find oscillator strengths from absorption spectra and for further calculation of radiative parameters such as the radiative lifetimes (τR), radiative transition probability (AR), total radiative transition probability (AT) and branching ratio (βR) to understand the quantum efficiency (η). Furthermore, the colorimetric parameters such as correlated color temperature (CCT), CIE coordinates and yellow to blue (Y/B) ratio were estimated from the PL emission data. The multipole-multipole interaction was confirmed by Dexter approximation to explain concentration quenching. This work primarily explains the essential features of borate glasses with Dy3+ ions doping to explain their potential use in tricolor w-LEDs and lasers.

Effect of fluorine substitution on the structure and spectral property of fluorotellurite glass for upconversion luminescence thermometry

A series of TeO2–ZnO–ZnF2–La2O3–Yb2O3–Er2O3 glasses (TZL) with different amount of ZnF2 were prepared by the melt quenching method. The effects of fluorine concentration on the density, refractive index, thermal behavior, and vibrational characteristic of TZL glasses were analyzed. The Judd-Ofelt (J-O) theory was employed to study the spectroscopic properties of Er3+ ions. By using the J-O intensity parameters the spontaneous radiative transition probabilities, fluorescence branching ratios, and radiative lifetimes of some concerned transitions of Er3+ were predicted. The potential of TZL glasses for the gain around 1.5 μm was briefly evaluated. Moreover, the upconversion luminescence was investigated under the excitation of 980 nm laser. The dependence of luminescence intensity on pump power revealed that the upconversion luminescence of Er3+ in TZL glasses are contributed by two-photon involved energy transfer processes. Furthermore, the adjacent upconversion green emissions of Er3+ ions were used to temperature sensing based on the fluorescence intensity ratio (FIR) technique. High absolute sensitivity and resolution have been obtained, which indicate that the TZL glasses are potential materials for optical fiber temperature sensors.

Investigation of luminescence properties of Ho3+ doped barium, zinc and gadolinium based phosphate glasses

10BaO-10ZnO-10Gd2O3-69P2O3-1Ho2O3 (ZBOH) and 10BaO-10ZnO-10GdF3-69P2O3-1Ho2O3 (ZBFH) were developed by the melt-quenched-method. The synthesized ZBOH and ZBFH glass samples were characterized for Uv-Vis-NIR, excitation, emission, decay time profile measurements and physical properties. It is observed that the ZBOH glass have higher density and refractive index as compared to the ZBFH glass. From the band gap calculation, it is observed that the oxyfluoride glasses have lower band gap as compared to the oxide glasses which indicate more \ on bridging oxygen in oxyfluoride glasses. The emission spectra recorded at λex = 449 nm show four emission bands at 5F2 (477 nm), 5F3 (495 nm),5F4 +5S2(545 nm) and5F5 (659 nm) from 5I8-levels. Judd-Ofelt (J-O) theory is used to investigate the J-O intensity parameters, transition probability, stimulated emission cross section and branching ratio. From the results it’s perceived that the radiative transition probability and branching ratio values are higher for 5F4 →5I8 transition as compared to the other transitions.

Radiative transition probabilities of neutral and singly ionized Europium estimated by laser-induced breakdown spectroscopy (LIBS)

Laser-induced breakdown spectroscopy (LIBS) is a versatile technique for compositional analysis for solids, liquids, or gasses. LIBS is an asset for the quantitative or qualitative analysis of resource limited materials like actinides and rare earths because it is quasi-nondestructive. Two Eu2O3 pellets were synthesized to be a test and validation set, respectively. Spectral lines identified from the National Institute of Standards and Technology database with fundamental data reported were used to form Saha-Boltzmann plots. The Saha-Boltzmann plots were used to determine the plasma temperatures and electron densities of the laser-induced plasmas for both samples. These Saha-Boltzmann plots were then used to calculate previously unreported transition probabilities associated with identified peaks. The transition probabilities presented in this paper provide the capability for calibration free LIBS to be performed more readily on europium samples and the spectroscopic analysis of stellar bodies. Eight previously unreported transition probabilities are presented in this paper; five for Eu I and three for Eu II. The transition probabilities for Eu I ranged from 0.172 to 7.38 × 107 s−1 and those for Eu II ranged from 1.56 to 6.75 × 107 s−1.
