Spectroscopy Characteristics of Samarium Oxide Doped Zinc Bismuth Barium Tellurite Glasses

Abstract

The zinc bismuth barium tellurite glasses system doped samarium oxide with chemical composition of (68–x) TeO2 – 10ZnO – 2Bi2O3 – 20BaO – xSm2O3, where x are 0.00 0.05 0.10 0.50 1.00 and 1.50 in mol% have been synthesized by conventional melt quenching technique at room temperature at 950 oC for 1 hour. This research study on spectroscopy properties. In order to study the role of Sm2O3 in zinc bismuth barium tellurite glass systems. The results shown that the density increased whereas the molar volume decreased with increasing of Sm2O3 concentrations. The optical absorption spectra of glasses were measured in the wavelength range of 500 – 2,000 nm for Sm3+ ion, the intensity of all absorption bands increased with increasing Sm2O3 content. In addition, the luminescence properties of Sm2O3 doped zinc bismuth barium tellurite glass systems were carried out using excitation wavelengths of 403 nm the luminescence peaks around 599 nm.
