Concentration Dependence of Sm 2 O 3 on Physical, Optical and Luminescence Properties of Na 2 O:Al 2 O 3 :Gd 2 O 3 :P 2 O 5 Glass System

AbstractThe 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 4G5/2 to 6H7/2 radiation transition of Sm3+ was generated under 275 and 402 nm excitation. The glass has an interesting potential photonic application.Keywords: SamariumEnergy TransferLuminescence Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingO.
