Abstract
⺠FTIR spectra reveal the presence of BO3 and BO4 non-bridging oxygen as well as strong OHâ bonds in the prepared glasses. ⺠Lower values of the Ω2 JO parameter exhibits asymmetric nature of the ion site. ⺠Higher stimulated emission cross-section value is the attractive feature for low threshold, high gain laser applications. ⺠Among the prepared glasses, Sm3+:B4TS glass is found to be suitable for developing the visible laser applications. ⺠The quantum efficiency of the 4G5/2 fluorescent level is found to be less due to the cross relaxation between the pair of Sm3+ ions.
