摘要

The melt quenching technique was used to fabricate new glasses with the chemical composition 70B2O3 – 20Li2O – (10–x) Al2O3 – xGd2O3 (where x = 0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, and 0.7 in mol%). The X-ray diffraction proved the material’s amorphous nature. Physical characteristics are calculated using the proper formulas. To find the functional groups contained in the material, Fourier transform infrared studies are conducted in order to look into the structural changes within the samples, and Raman spectra were taken between 400 and 4000 cm−1. Using a UV-Visible spectrophotometer, the spectra of absorption in the 200 nm to 1100 nm wavelength range have been recorded. The optical band gap was assessed using Tauc’s plots, and the relationship between the optical energy gap and the concentration of Gd3+ ions has been examined. Dimitrov and Sakka’s relationship discovered the indices of refraction for these manufactured glasses. By using the proper formulas, physical parameters were calculated. The concentration of Gd3+ ions was used to analyze the data that were obtained. At various wavelengths for excitation and emission, the photoluminescence spectra have been noted to determine the emission property. On plotting the CIE-chromaticity coordinates with PL intensity, it was revealed that in the white light range.
