Abstract
In the present work, different concentrations of Sm3+-doped strontium lithium bismuth borate glasses (SLBiB) were prepared by melt quench technique. The amorphous nature of the prepared glass samples was confirmed by X-ray diffraction and SEM analysis. Using the J-O intensity parameters, emission and decay measurements various radiative properties are studied. The nature of decay curves of 4G5/2 level for different Sm3+ ion concentrations in SLBiB glasses has been analyzed. The intensities of observed emission peaks and measured lifetimes decrease with the increase of Sm3+ ion concentration which may be due to energy transfer between excited Sm3+ ions through cross-relaxations and resonant energy channels.
