“…Moreover, due to their lower toxicity, antimony-containing systems are preferable for medical applications than compositions with arsenic [14]. This made the Se-Ge-Ga-Sb system an attractive alloy for storage applications and is also known as a potential material for mid-IR fiber [17]. Sb also enhances the optical properties of the Se-Ge-Ga system; It reduces E g (the optical band-gap energy) [13].…”

A quenching technique was used to prepare the chalcogenide system of the Se60−xGe35Ga5Sbx (x = 0, 5, and 10 at. %), which was deposited as thin films onto glass substrates using a thermal evaporation technique. X-ray diffraction patterns were used for structure examination of the fabricated compositions, which exposes the amorphous nature of the deposited samples. Meanwhile, the chemical compositions of the prepared samples were evaluated and calculated via the energy-dispersive X-ray spectroscopy (EDX), which was in agreement with the measured compositional element percentages of the prepared samples. Based on the optical reflectance R and transmittance T spectra from the recorded spectrophotometric data ranging from 350 to 2500 nm, the influence of the Sb element on the Se60−xGe35Ga5Sbx thin films’ optical properties was studied. The film thickness and the refractive index were calculated via Swanepoel’s technique from optical transmittance data. It has been observed that the films’ refractive index increases with increasing x value over the spectral range. The refractive index data were used to evaluate the dielectric constants and estimate dispersion parameters Eo and Ed using the Wemple–DiDomenico model. The optical energy gap Egopt was calculated for the tested compositions. The result of the optical absorption analysis shows the presence of allowed direct and indirect transitions.

Glass samples with the composition 40 Bi2O3-60 GeO2-x Er2O3 are prepared using the melt quenching procedure. Fourier-transform infrared spectroscopy (FTIR), differential thermal analysis (DTA), Ultraviolet/Visible/Near-infrared (UV/Vis–NIR) absorption, photoluminescence spectroscopy (PL), and X-ray diffraction (XRD) are used to characterize the glass and glass–ceramic materials. The glass transition and crystallization temperatures are determined. Crystallization kinetics was studied in non-isothermal conditions. The oscillator strengths and Judd–Ofelt parameters (Ω2, Ω4, Ω6) for reported Er3+ absorption transitions are estimated, and they follow the trend Ω2 > Ω6 > Ω4 for observed Er3+ absorption transitions. The iconicity of glass samples was unaffected by an increase in Er3+ ions. XRD and FTIR confirmed the formation of the Bi4Ge3O12 phase after heat treatment of glass samples at the crystallization temperature. The CIE chromaticity diagram computes the CIE chromatic coordinates. The values for all glass and crystal samples are close to bright blue and green. Glass and glass ceramic samples are suitable for green and blue optoelectronics device applications.
