Abstract

Lithium yttrium borate glasses doped with samarium ions (LiYBO:Sm³⁺) were prepared by using melt-quenching for different Sm₂O₃ concentrations. The spectroscopic properties were investigated by using absorption, emission and decay curve measurements. Density and molar volume of LiYBO:Sm³⁺ glasses increased with increasing Sm₂O₃ concentration. The glasses absorbed photons in the visible light (VIS) and near-infrared (NIR) regions. For the photoluminescence property, the glasses showed the strongest emission at 600 nm when they were excited by 403 nm photons. The optimum concentration of Sm₂O₃ in LiYBO glass is 0.50 mol% which exhibited the highest intensity of emission. The lifetime values decreased with increasing Sm³⁺ ion concentration which is due to energy transfer through cross-relaxation. The non-exponential decay curves are well fitted by the Inokuti-Hirayama model for S=6, indicating that the interaction for cross-relaxation is of the dipole-dipole type.
