Abstract
In this work, the physical, optical properties of Sm3+ doped glass made from rice husk ash (RHA) with different concentrations of Sm3+ ion were prepared. The glass samples with chemical composition of (60-x) SiO2: 30B2O3:10Na2O: 10CaO: xSm2O3 were prepared by melting-quenching process (use RHA as a SiO2) . Density and molar volume of the sample glass increase with increasing of Sm3+ concentration. The absorption spectra found peak absorbs in the UV-Vis-NIR region. Main emission peak was observed at 600 nm under excitation at 401 nm. The emission color of glasses were confirmed by CIE 1931 color coordinates and are in the orange region emission. The results show the potential of Sm3+ doped glass made form rice husk is useful in future photonics application.
