Study on Optical Properties of Lithium Barium Bismuth Phosphate Glasses Doped with Sm3+ ions

Abstract

Lithium barium bismuth phosphate (LBBP) glasses doped with samarium oxide were prepared by melt quenching technique at 1000 0C. The absorption spectra of LBBPSm glasses were recorded in the UV-Vis-NIR region at room temperature. All the absorption transitions originated from 6H5/2 ground state to the various excited state including 4D3/2, 4L17/2, 4L15/2, 6P3/2, 4M19/2, 6P5/2, 4G9/2, 4F5/2, 4I13/2, 4I11/2, 4M15/2, 4I9/2, 4G7/2, 4F3/2, 4G5/2, 6F11/2, 6F9/2, 6F7/2, 6F5/2, 6F3/2, 6H15/2, and 6F1/2 excited states, respectively. Also, it was found that the shape of the absorption peaks were similar in all glasses. Only minimal variations of peak intensity were observed.
