Sm3+ Doped Borotellurite Glass: Absorption, Fluorescence and Optical Parameters Authors: Phan, Van Do Borotellurite glasses doped with Sm3+ ions were prepared by a melt–quenching technique. The studies on optical characterization of Sm3+ ions have been carried out through absorption, emission and decay spectra. Judd-Ofelt (JO) intensity analysis has been presented and JO parameters were calculated for Sm3+ ions in borotellurite glasses. Radiative properties such as transition probabilities, branching ratios, radiative lifetime of 4G5/2 level and quantum efficiency were estimated by using JO parameters...
