Concentration Dependence of Sm₂O₃ on Physical, Optical and Luminescence Properties of Na₂O:Al₂O₃:Gd₂O₃:P₂O₅ Glass System

Abstract

The Na₂O:Al₂O₃:Gd₂O₃:P₂O₅ glasses were doped with different concentrations of Sm³⁺ ions and synthesized by the melt-quenching technique. These glasses were investigated to characterize physical and spectroscopy analyses that have been carried out by density, molar volume, absorption, FTIR, and photoluminescence measurements. The density and molar volume of glasses increases with the addition of Sm₂O₃ concentration. Glasses absorbed photons in UV, VIS, and NIR regions. The strong orange emission via the ⁴G_5/2 to ⁶H_7/2 radiation transition of Sm³⁺ was generated under 275 and 402 nm excitation. The glass has an interesting potential photonic application.
