This paper was to investigate the optical and luminescence properties of Sm^(3+) doped SLB glasses by a melt quenching technique. The optical and luminescence properties of the prepared glass samples were investigated via absorption and photoluminescence spectra, respectively. The related physical and optical parameters were also calculated. From optical absorption measurements, the transition ~6H_(5/2) → ~6P_(3/2) at 403 nm has a higher spectral intensity and is a hypersensitive transition. From photoluminescence spectra, four prominent emission spectra appear. The most intense band is located at ~4G_(5/2) →~6H_(9/2)(599 nm), which is the characteristic emission range of Sm^(3+) ions with the reddish orange color. The experimental decay time of the ~4G_(5/2) level of Sm^(3+) SLB glasses was determined. The decay time decreases from 1.367 to 0.333 ms with increasing the content of Sm^(3+). The color coordinates(x, y) of the prepared glasses passes through the reddish-orange region in the CIE 1931 diagram and are suitable for orange LEDs, optoelectronics, and solidstate lighting. The further investigation on the optimization of the dopant content in the SLB glasses was suggested.
