Synthesis and Characterization of Novel Sm2O3-Doped Zinc Barium Strontium Niobium Boro-Tellurite Glass for Optical Applications

Abstract

A series of zinc barium Strontium niobium borotellurite glasses doped with Samarium Oxide glasses of the compositions (30-x)TeO2 –30B2O3 –10ZnO –10SrO - 10BaO –10Nb2O5 – x Sm2O3 (where x = 0.00 0.10 0.50 1.00 1.50 mol%) have been synthesized by conventional melt quenching technique at 1150 degree celsius for 1.5 hours. This research studies on to the physical, optical and luminescence to understand the role of borotellurite glasses doped with properties samarium oxide glasses systems; the results shown that the density and molar volume no trend as Sm2O3 doped in glasses system on effect to that result, the values of density between 3.8221 ± 0.0045 to 3.8879 ± 0.0024 g/cm3 and the values of molar volume between 34.5534 to 35.8410 cm3/mol. The refractive index changes with density, with the refractive index ranging from 1.634 to 1.720. The optical absorption spectra of glasses were measured in the wavelengths range of 480 - 2,500 nm. The intensity of absorption increased with increasing of Sm2O3 content. In addition, the luminescence properties of Sm2O3 doped zinc barium Strontium niobium borotellurite glasses stem were carried out using excitation wavelengths of 403 nm. The luminescence peaks around 563, 598, 644 and 705 nm were observed. The analysis of CIE 1931 chromaticity showed that the light emitting from this glass is orange.
