Abstract

Sm3+-doped bismuth borate glasses of the composition (50-x) SiO2: 50B2O3: xSm2O3 (where x = 0.00, 0.50, 1.00, 1.50, 2.00 and 2.50 mol%) have been synthesized by conventional melt quenching technique. In order to understand the role of Sm2O3 in bismuth borate glasses, the density, molar volume, refractive index and optical absorption were investigated. The results show that density, molar volume and refractive index of glasses increased with increasing Sm2O3 concentration. The increase of molar volume with Sm2O3 concentration is due to the increase of Non-Bridging Oxygen (NBOs) in the glass matrix. The optical absorption spectra were measured in the wavelength range from 300-1100 nm and the optical band gaps were determined. It was found that the optical band gap decreased with the increase of Sm2O3 concentration. Moreover, the x-rays luminescence of Sm2O3 glasses samples were measured and shows emission band at 4G5/26H5/2 (569 nm), 4G5/26H7/2 (598 nm), 4G5/26H9/2 (641 nm) and 4G5/26H11/2 (705 nm). This investigation have been used as the basis for developing optical amplifier or glass scintillator.
