Physical, optical, and luminescent characteristics of Sm3+ doped tellurite glass suitable for yellow laser, warm white LED, and radiation shielding applications

Abstract

The glass containing the following compositions: Te₂O₃ − B₂O₃ − Li₂CO₃ − ZnO − NaF: Sm₂O₃ were made using the melt-quench process and identified as Sm³⁺ Tellurite glass. The present work shows their Physical, optical, luminescent, and radiative characteristics in this paper. The glass’s amorphous form was confirmed by an analysis of powder X-ray diffraction. Fourier transform infrared spectroscopy was used to identify the functional groups of glass. The glass was inspected using ultraviolet–visible spectroscopy and JO analysis was discussed. Its refractive index and optical band gap were among these characteristics. Emission peaks at 565 nm, 600 nm, and 646 nm were seen in the emission spectra. Based on the Commission International de l’éclairage (CIE 1931) diagram, all samples’ color coordinates showed outstanding emission between neutral white and sunshine white, suitable for yellow laser. Using the Phy-X program, the mass attenuation coefficient, half-value layer, mean free path, tenth value layer, and energy absorption buildup factor (EABF) were examined about the glass’s gamma-ray shielding properties.
