Silver Nanoclusters Tunable Visible Emission and Energy Transfer to Yb3+ Ions in Co-Doped GeO2-PbO Glasses for Photonic Applications.

This work investigates the optical properties of Yb3+ ions doped GeO2-PbO glasses containing Ag nanoclusters (NCs), produced by the melt-quenching technique. The lack in the literature regarding the energy transfer (ET) between these species in these glasses motivated the present work. Tunable visible emission occurs from blue to orange depending on the Yb3+ concentration which affects the size of the Ag NCs, as observed by transmission electron microscopy. The ET mechanism from Ag NCs to Yb3+ ions (2F7/2 → 2F5/2) was attributed to the S1→T1 decay (spin-forbidden electronic transition between singlet-triplet states) and was corroborated by fast and slow lifetime decrease (at 550 nm) of Ag NCs and photoluminescence (PL) growth at 980 nm, for excitations at 355 and 405 nm. The sample with the highest Yb3+ concentration exhibits the highest PL growth under 355 nm excitation, whereas at 410 nm it is the sample with the lowest concentration. The restriction of Yb3+ ions to the growth of NCs is responsible for these effects. Thus, higher Yb3+ concentration forms smaller Ag NCs, whose excitation at 355 nm leads to more efficient ET to Yb3+ ions compared to 410 nm. These findings have potential applications in the visible to near-infrared regions, such as tunable CW laser sources and photovoltaic devices.

Electronic, Optical, Thermoelectric and Elastic Properties of RbxCs1-xPbBr3 Perovskite.

Inorganic halide perovskites of the type AMX3, where A is an inorganic cation, M is a metal cation, and X is a halide anion, have attracted attention for optoelectronics applications due to their better optical and electronic properties, and stability, under a moist and elevated temperature environment. In this contribution, the electronic, optical, thermoelectric, and elastic properties of cesium lead bromide, CsPbBr3, and Rb-doped CsPbBr3, were evaluated using the density functional theory (DFT). The generalized gradient approximation (GGA) in the scheme of Perdew, Burke, and Ernzerhof (PBE) was employed for the exchange-correlation potential. The calculated value of the lattice parameter is in agreement with the available experimental and theoretical results. According to the electronic property results, as the doping content increases, so does the energy bandgap, which decreases after doping 0.75. These compounds undergo a direct band gap and present an energies gap values of about 1.70 eV (x = 0), 3.76 eV (x = 0.75), and 1.71 eV (x = 1). The optical properties, such as the real and imaginary parts of the dielectric function, the absorption coefficient, optical conductivity, refractive index, and extinction coefficient, were studied. The thermoelectric results show that after raising the temperature to 800 K, the thermal and electrical conductivities of the compound RbxCs1-xPbBr3 increases (x = 0, 0.25, 0.50 and 1). Rb0.75Cs0.25PbBr3 (x = 0.75), which has a large band gap, can work well for applications in the ultraviolet region of the spectrum, such as UV detectors, are potential candidates for solar cells; whereas, CsPbBr3 (x = 0) and RbPbBr3 (x = 1), have a narrow and direct band gap and outstanding absorption power in the visible ultraviolet energy range.

Black titanium dioxide nanocolloids by laser irradiation in liquids for visible light photo-catalytic/electrochemical applications

The discovery of defect induced TiO2 nanoparticles with enhanced visible light absorption has sparked an outburst of interest for visible energy applications. Here we report the formation of black titanium dioxide (BTO) nanoparticles in de-ionized water (DW), isopropyl alcohol (IPA) and DW-IPA mixture (1:1) using pulsed laser irradiation in liquids. X-ray diffraction showed the transformation of the major anatase phase in WTO (white TiO2) to rutile for BTO by irradiation. The presence of these phases was further confirmed by Raman spectroscopy. Transmission electron microscopy (TEM) was utilized for the morphology and structural confirmation. Scanning electron microscopy (SEM) showed the existence of nanoparticles with mixed shapes and sizes. X-ray photoelectron spectroscopy (XPS) acquired information on the chemical states present as well as elemental composition where shifts in Ti 2p as well as O 1s peaks are observed for BTO. Reduced bandgap and enhanced visible light absorption are observed in BTO by diffuse reflectance spectroscopy (DRS). Photocatalytic degradation studies showed superior organic dye decay activity under visible light for BTO. Photoelectrocatalytic activity of BTO films in neutral pH showed selectivity for oxygen evolution reaction (OER). These results show a facile fabrication of defect rich metal oxide nanomaterials with enhanced visible light activity.

Synthesis and characterization of NiO–Bi2O3 nanocomposite material for effective photodegradation of the dyes and agricultural soil pollutants

Synthesis and characterization of the pristine NiO, Bi2O3 and composite NiO–Bi2O3 (NBO) nano material systems with the modified surface morphology is reported. The NBO and pure oxide materials are thoroughly characterized with various spectroscopic methods such as XPS, p-XRD, FTIR, Raman, UV–vis-DRS, PL, FESEM and HRTEM analysis. XRD results showed the formation of a new γ-phase of Bi2O3 after incorporating Ni on its surface. XPS and EDX analysis confirmed the presence of both Ni2+ and Bi3+ in the nanoparticles. HRTEM analysis showed NiO nanospheres on Bi2O3 nanorods with 13–18 nm nanoparticle sizes Furthermore, as a result of composite phase formation, a substantial decrease in bandgap from 3.28 to 2.62 eV is found, which was captivating to study the visible light energy induced photodegradation of methylene blue (MB), methyl orange (MO) dyes and agricultural soil pollutants (ASP). The effect of pH, dosage, and scavenger's studies are investigated to establish the mechanism of the active species of the photodegradation process and which is supported by photocurrent and EIS studies. Under the optimal framework, the photocatalytic degradation efficacy of the MB, MO dyes and ASP degradation with NBO was 95, 90 and 94% respectively. Additionally, HPLC analysis of initial and final samples of dyes was studied and TOC analysis for ASP examined. NBO catalyst was recovered and reused umpteen times with marginal change in photocatalytic efficiency.

Visible luminescence and energy migration mechanism of Sm3+ in phospho-tellurite glasses by co-activating with Tb3+ ions for solid state lighting device applications

Luminescence characteristics including the energy migration mechanism of Sm3+/Tb3+ co-activated BaO–PbO–Na2O-phospho-tellurite glasses have been reported. The XRD, FTIR, UV–VIS-NIR absorption, luminescence and CIE are examined to expose their structural and optical properties. The luminescence spectra of Sm3+/Tb3+ co-doped glasses show the green emission (Tb3+ ions) and reddish-orange colour emission (Sm3+ ions) upon dual excitation at 377 nm and 484 nm. The reduction of emission intensities (Tb3+ions) and self-emission quenching effect of Sm3+ ions have been observed when concentration of Sm3+ ions increases into the glass matrix which reveals the evidence of non-radiative energy transfer from Tb3+ (sensitizer) to Sm3+ (activator) ions. The phenomenon of energy migration is also verified with the help of Forster-Dexter theory. The chromaticity coordinates of all Sm3+/Tb3+ co-activated glasses shift from greenish to yellowish region with dependence of activator's concentration. The paper highlights that the present glasses can be utilized in light emitting devices.

An advanced biosensor assembly based on glass fiber paper (GFP) electrodes modified with nanocomposites comprising of poly (3,4-ethylene dioxythiophene) polystyrene sulfonate (PEDOT: PSS) as the main matrix with functionalized gold nanoparticles (GFP/PEDOT: PSS-AuNP) for selective and sensitive detection of procalcitonin (PCT). PCT is a biomarker that is specifically used to detect bacterial infections, and it has received a lot of interest as a potential answer to the challenges with selecting when to use antibiotics. Field emission scanning electron microscopy, ultraviolet–visible spectroscopy and energy dispersive X-ray analysis characterization techniques were used to characterize the prepared PEDOT: PSS-AuNP nanocomposite.

In addition, the inclusion of AuNP in PEDOT: PSS resulted in improved electrochemical performance and signal stability. This PEDOT: PSS-AuNP@GFP platform based was used to immobilize anti-PCT antigenic protein for PCT quantification. The results of electrochemical response studies showed that this conductive paper bioelectrode had a good reproducibility sensitivity in physiological ranges (1–15 pg mL−1). Further, the proposed bioelectrode an alternative choice for point-of-care PCT detection has been shown.

Pulse shape discrimination using a convolutional neural network for organic liquid scintillator signals

A convolutional neural network (CNN) architecture is developed to improve the pulse shape discrimination (PSD) power of the gadolinium-loaded organic liquid scintillation detector to reduce the fast neutron background in the inverse beta decay candidate events of the NEOS-II data. A power spectrum of an event is constructed using a fast Fourier transform of the time domain raw waveforms and put into CNN. An early data set is evaluated by CNN after it is trained using low energy β and α events. The signal-to-background ratio averaged over 1–10 MeV visible energy range is enhanced by more than 20% in the result of the CNN method compared to that of an existing conventional PSD method, and the improvement is even higher in the low energy region.

Insights into visible luminescence and energy transfer mechanism of Eu3+/Dy3+ co-doped dolo-telluro-borate glasses

A series of Eu3+/Dy3+co-doped doro-telluro-borate (DTB) glasses were prepared using the melt-quenching approach and characterized. The absorption, excitation, emission, CIE1931 diagram and fluorescence decay profiles of these glasses were examined. The Judd-Ofelt model calculation was performed. These glasses showed prominent visible luminescence and lasing potency. The emission spectra and fluorescence lifetime decay profiles of the glasses with the increase of Dy3+ suggested an efficient energy transfer process between Eu3+ and Dy3+. The obtained chromaticity coordinates and color correlated temperature (CCT) of these glasses confirmed the emission of reddish-orange tone useful for cool white light displays. It was shown that the multicolor light emission from the studied glasses can be tuned by properly adjusting the Eu3+/Dy3+ co-doping contents. The proposed glass compositions may be advantageous for the construction of low-cost solid-state laser and cool white light emitting diodes.

A comparative study on structural, magnetic and optical properties of rare earth ions substituted Bi1−x R x FeO3 (R: Ce3+, Sm3+ and Dy3+) nanoparticles

Abstract A comparative study on the manifestation of rare earth ions substitution induced alteration in structure, magnetic and optical properties of BiFeO3 nanoparticles was done. Sol-gel technique was employed to synthesize Bi1−x R x FeO3 (x = 0.05 and 0.10; R: Ce3+, Sm3+ and Dy3+) nanoparticles. X-ray diffraction patterns and Raman spectra analysis confirmed substitution driven structural phase transformation from distorted rhombohedral structure to orthorhombic structure for x = 0.10 samples. The enhanced magnetic properties with weak ferromagnetic behaviour were observed with increasing concentration of rare earth ions in BiFeO3 nanoparticles. The improved magnetic characteristics are attributed to many factors such as the uncompensated surface spins in nanoparticles, breaking of spin cycloid with R 3+ ions substitution and super exchange interaction between R 3+ and Fe3+ ions. The maximum magnetization values of 1.77 emu g−1, 1.87 emu g−1 and 5.5 emu g−1 were observed for x = 0.10 samples with Ce3+, Sm3+ and Dy3+ substitution, respectively. The magnetization increased with increasing difference in ionic radii of host Bi3+ (1.17 Å) ion and dopant Ce3+ (1.14 Å), Sm3+ (1.08 Å) and Dy3+ (1.03 Å) ions. UV–Visible diffuse reflectance spectra showed a sharp absorption in visible region and energy band gap values variation in the range 2.2 eV–2.33 eV.

Geometric, electronic and transport properties of bulged graphene: A theoretical study.

Out-of-plane deformation in graphene is unavoidable during both synthesis and transfer procedures due to its special flexibility, which distorts the lattice and eventually imposes crucial effects on the physical features of graphene. Nowadays, however, little is known about this phenomenon, especially for zero-dimensional bulges formed in graphene. In this work, employing first-principles-based theoretical calculations, we systematically studied the bulge effect on the geometric, electronic, and transport properties of graphene. We demonstrate that the bulge formation can introduce mechanical strains (lower than 2%) to the graphene's lattice, which leads to a significant charge redistribution throughout the structure. More interestingly, a visible energy band splitting was observed with the occurrence of zero-dimensional bulges in graphene, which can be attributed to the interlayer coupling that stems from the bulged structure. In addition, it finds that the formed bulges in graphene increase the electron states near the Fermi level, which may account for the enhanced carrier concentration. However, the lowered carrier mobility and growing phonon scattering caused by the formed bulges diminish the transport of both electrons and heat in graphene. Finally, we indicate that bulges arising in graphene increase the possibility of intrinsic defect formation. Our work will evoke attention to the out-of-plane deformation in 2D materials and provide new light to tune their physical properties in the future.

In-situ immobilization of Ag/AgCl on sulfurized g-C3N4 nanosheet for enhancing visible-light driven photocatalysis toward simultaneous oxidation of tetracycline and reduction of Cr(VI) in water

The Ag/AgCl-S@CN photocatalyst was successfully prepared by in-situ formation of Ag/AgCl nanoparticles on the sulfurized g-C3N4 nanosheets. The catalytic activity of the photocatalyst was thoroughly explored by simultaneous photocatalytic oxidation of tetracycline (TC) and reduction of chromate, Cr(VI), under visible light. The results demonstrated that the photocatalytic composite could harvest visible light energy and facilitate charge separation efficiency due to the presence of abundant active sites, which ultimately enhanced the photocatalytic oxidation of TC and reduction of Cr(VI). The Z-scheme heterojunction, provided mainly h+ and O2•− for TC oxidation and e− for Cr(VI) reduction concurrently. Moreover, the photocatalyst enabled effective concurrent conversion of TC and Cr(VI) in a wide pH range. LC/MS-MS study of intermediates revealed the major TC photocatalytic breakdown routes, which included hydroxylation, oxidation, cleavage and demethylation. This study provides new perspectives into the approaches for the creation and application of Z-scheme heterojunction-based nanocomposites in the simultaneous removal of diverse hazardous contaminants from the environment.

Optically heated blackbody emitter for dynamic infrared scene generation

The infrared image conversion chip based on optical heating technique has advantages of wide spectral range and high spatial resolution, which is appropriate as an infrared target simulator. At present, the dynamic infrared image, which is physically generated by infrared target simulator, can achieve 8-bit grayscale level with 100 Hz refresh rate. In this paper, we demonstrate an optically heated blackbody emitter (OHBE) for dynamic infrared scene generation to further improve the grayscale level of generated infrared image. The OHBE utilizes the thermal inertness of radiation layer material to integrate the visible light energy, and generates infrared images with 10-bit grayscale value within 1.25 ms. And the infrared images can be collected in a holding time of 3.75 ms in each refresh cycle. The temperature range of the generated infrared image is 108 K, and the temperature resolution corresponds to a unit grayscale value is 0.1 K. The OHBE proposed has been successfully applied to an infrared target simulator.

Magnetic-field switching of second-harmonic generation in noncentrosymmetric magnet Eu2MnSi2O7

We report a giant magnetic-field effect on optical second-harmonic generation (SHG) in a noncentrosymmetric ferrimagnet ${\mathrm{Eu}}_{2}\mathrm{Mn}{\mathrm{Si}}_{2}{\mathrm{O}}_{7}$. The SHG intensity changes at visible photon energy of 2.8 eV by more than 7000% upon the reversal of magnetic-field direction. Such pronounced modulation of the nonlinear optical activity results from an interference between crystallographic and magnetically induced nonlinear polarization. The amplitude of these nonlinear optical susceptibilities is controlled by the spin alignment and the light incident angle, enabling to optimize the magnetic switching of SHG in detail.

Rats lacking Ucp1 present a novel translational tool for the investigation of thermogenic adaptation during cold challenge.

Valuable studies have tested the role of UCP1 on body temperature maintenance in mice, and we sought to knockout Ucp1 in rats (Ucp1-/- ) to provide insight into thermogenic mechanisms in larger mammals. We used CRISPR/Cas9 technology to create Ucp1-/- rats. Body weight and adiposity were measured, and rats were subjected to indirect calorimetry. Rats were maintained at room temperature or exposed to 4°C for either 24 h or 14 days. Analyses of brown and white adipose tissue and skeletal muscle were conducted via histology, western blot comparison of oxidative phosphorylation proteins, and qPCR to compare mitochondrial DNA levels and mRNA expression profiles. RNA-seq was performed in skeletal muscle. Ucp1-/- rats withstood 4°C for 14 days, but core temperature steadily declined. All rats lost body weight after 14 days at 4°C, but controls increased food intake more robustly than Ucp1-/- rats. Brown adipose tissue showed signs of decreased activity in Ucp1-/- rats, while mitochondrial lipid metabolism markers in white adipose tissue and skeletal muscle were increased. Ucp1-/- rats displayed more visible shivering and energy expenditure than controls at 4°C. Skeletal muscle transcriptomics showed more differences between genotypes at 23°C than at 4°C. Room temperature presented sufficient cold stress to rats lacking UCP1 to activate compensatory thermogenic mechanisms in skeletal muscle, which were only activated in control rats following exposure to 4°C. These results provide novel insight into thermogenic responses to UCP1 deficiency; and highlight Ucp1-/- rats as an attractive translational model for the study of thermogenesis.

Red shift of lead-free halide perovskite RbCaCl3 under pressure for enhancing optoelectronic performance

This study focuses on the exploration of pressure effects on the structural, electronic, optical, and mechanical properties of a cubic halide perovskite RbCaCl3 using density functional theory. The calculated values of lattice constant and unit cell volume at zero pressure are justified by the previous experimental and theoretical studies. As pressure is applied both the lattice constant and unit cell volume decrease steadily because of bond length reduction inside the material. The indirect band gap nature of the studied perovskite transforms into direct under applied pressure of 40 GPa and more. Moreover, the band gap value significantly reduces under pressure effect from ultraviolet to visible energy region. Though the bonding nature of both Rb−Cl and Ca−Cl is initially ionic, the induced pressure slightly reduces the ionicity of Rb−Cl and makes the Ca−Cl bond covalent. The optical absorption reveals a red shift in the visible energy region advantageous for using RbCaCl3 in solar cell applications. In addition, the overall optical analysis reveals that the pressure-induced compound is more suitable for optoelectronic device applications than that of zero pressure system. The external hydrostatic pressure significantly affects the mechanical properties of titled compound, making it more ductile and anisotropic.

Preparation of visible light-WO3/g-C3N4/PANI photocatalyst onto glass and their photocatalytic properties

Wastewater from palm oil industry mostly contains hazardous effluent like palm oil mill effluent (POME) and photocatalytic technology is one of the most effective ways for the degradation of harmful organic pollutants. Nevertheless, the effects of suspended photocatalysts obviously would dwindle the photocatalytic performances. The immobilization of photocatalyst as a newest innovation has received significant attention due to its great potential in terms of recycling, economic, physical–chemical properties, and technological aspects. This paper reports the synthesis of novel WO3/g-C3N4/PANI glass as a retrievable visible-light photocatalyst by simple soft-templating and calcination followed by spin coating with different speed and duration coating. The functional group of O-W-O stretching vibration, hydrophilicity of the immobilized WO3/g-C3N4/PANI glass indicated the presence of WO3/g-C3N4/PANI onto glass was succesfully. The optimum parameters obtained were at a speed of 30 s and duration spinning of 1000 rpm due to the presence of more active sites. In particular, immobilized WO3/g-C3N4/PANI glass showed a good photocatalytic activity in term of decolorization and degradation studies about 25 % and 53 %, respectively, after 7 h under visible light irradiation and energy storage scheme. The results signify possible applications of immobilized WO3/g-C3N4/PANI glass in visible-light-driven and energy-storage-mechanism for a cost-effective treatment of wastewater.

Zinc Vanadate (Zn3V2O8) Immobilized Multiwall Carbon Nanotube (MWCNT) Heterojunction as an Efficient Photocatalyst for Visible Light Driven Hydrogen Production.

Z-scheme photocatalytic reaction is considered an effective strategy to promote the photogenerated electron-hole separation for significantly improving the efficiency of photocatalytic hydrogen precipitation from splitting water. In this study, a heterojunction nanocomposite material based on Zn3V2O8 (ZV) with MWCNT was prepared by a hydrothermal process. The photocatalysts were characterized by X-ray diffraction, scanning electron microscopy (SEM), Fourier transform infrared (FTIR), UV-visible absorption spectroscopy, and transmission electron microscopy (TEM) to understand crystal structure, morphology, and optical properties. The efficiency of the samples was evaluated for the photocatalytic H2 production under visible solar radiation using water glycerol as a sacrificial reagent. The obtained results suggest that, between ZV and ZV@MWCNT, the latter shows higher efficiency for H2 production. The maximum H2 production efficiency was found to be 26.87 μmol g-1 h-1 for ZV and 99.55 μmol g-1 h-1 for ZV@MWCNT. The synergistic effect of MWCNT to ZV resulted in improving the efficiency of charges and light-absorbing capacity, resulting in enhanced H2 production in the heterojunction nanocomposite material. The nanocomposite was stable and highly efficient for H2 production of six or more cycles. Based on the outcomes of this study, it can be observed that forming the heterojunction of individual nano systems could result in more efficient material for H2 production under visible solar energy.

Acid-Triggered Switchable Near-Infrared/Shortwave Infrared Absorption and Emission of Indolizine-BODIPY Dyes.

Fluorescent organic dyes that absorb and emit in the near-infrared (NIR, 700-1000 nm) and shortwave infrared (SWIR, 1000-1700 nm) regions have the potential to produce noninvasive high-contrast biological images and videos. BODIPY dyes are well known for their high quantum yields in the visible energy region. To tune these chromophores to the NIR region, fused nitrogen-based heterocyclic indolizine donors were added to a BODIPY scaffold. The indolizine BODIPY dyes were synthesized via microwave-assisted Knoevenagel condensation with indolizine aldehydes. The non-protonated dyes showed NIR absorption and emission at longer wavelengths than an aniline benchmark. Protonation of the dyes produced a dramatic 0.35 eV bathochromic shift (230 nm shift from 797 nm to 1027 nm) to give a SWIR absorption and emission (λmaxemis = 1061 nm). Deprotonation demonstrates that material emission is reversibly switchable between the NIR and SWIR.

Synthesis and characterization of linear/nonlinear optical properties of graphene oxide and reduced graphene oxide-based zinc oxide nanocomposite

In this paper, we aimed to investigate the linear and nonlinear optical properties of GO-ZnO and RGO-ZnO nanocomposites in comparison with pure GO and reduced graphene oxide (RGO). For this purpose, GO, RGO, GO-ZnO, and RGO-ZnO were synthesized and characterized by Fourier transform infrared (FT-IR), Ultraviolet–Visible (UV–Vis) absorption, X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDX). XRD and EDX analysis indicated the reduction of GO as well as the successful synthesis of GO-ZnO and RGO-ZnO nanocomposites. The FT-IR spectroscopy showed that absorption bands were at 3340 cm−1, 1630 cm−1, 1730 cm−1 and 480 cm−1 related to OH, C=C, C=O, and Zn–O stretching vibrations, respectively. The direct band gaps of GO, RGO, GO-ZnO and RGO-ZnO from UV–Vis spectra were at 3.36, 3.18, 3.63 and 3.25 eV, sequentially. Moreover, the third-order nonlinear optical properties were investigated using a z-scan technique with Nd: YAG laser (532 nm, 70 mW). It can be seen that the nonlinear absorption coefficient value (upbeta ) increased from 5.3 × 10–4 (GO) to 8.4 × 10–3 cm/W (RGO-ZnO). In addition, nonlinear refractive index (n2) of the GO, RGO, GO-ZnO, and RGO-ZnO was obtained as 10.9 × 10–10, 14.3 × 10–10, 22.9 × 10–10, and 31.9 × 10–10 cm2/W respectively.

Investigation of structural and optical properties of In-doped AlSb nanostructures

The first-principles calculations are made to study the structural electronic and optical properties of indium-doped aluminum antimonide. The most appropriate method of density functional theory (DFT) naming Full Potential Linearized Augmented Plane Wave (FP-LAPW) is used. The structural properties like Lattice constant (a), pressure derivative, and bulk modulus (B) were examined by Local density approximation (LDA) along with generalized gradient approximation (GGA). Generalized gradient approximation along with TB-mBJ is used to determine electronic parameters like band structure along and density of states. According to the computed results the binary compound AlSb is optically inactive and exhibits an indirect (Γ-L) band gap. By increasing the concentration of indium with different percentages, the indirect band gap shifted to the direct (Γ – Γ) band gap which shows the material is optically active. The optical properties of the material including dielectric (Real and imaginary parts) constant, reflectivity, refractive index, energy loss, absorption coefficient, and optical conductivity have changed significantly. Electronic and optical properties are modified by (TB-mBJ) approach. The results obtained are examined with experimental data and utilized as a starting point to propose that the material is the superlative choice for the manufacturing of p-n junctions, photo-detectors, laser, photo-diodes, transistors and solar spectrum absorptions in the visible, infrared and ultraviolet energy ranges.
