Abstract
SM3+–doped borate glasses were synthesized using the melt–quenching method, and luminescence characteristics were systematically investigated. Initially, the glass composition was modified by varying the Bi2O3 content while maintaining the SM3+ concentration at 1.00 mol%. Optical absorption measurements revealed that BiBaTB1Sm glasses exhibited a prominent peak at 401 nm in the visible region, which was selected as the excitation wavelength for photoluminescence analysis. The emission spectra demonstrated a maximum intensity at 598 nm under 401 nm excitation. Notably, the glass sample without Bi2O3 showed stronger emission compared to the Bi2O3-doped counterparts. In a separate study, the SM3+ concentration was varied (0.0, 0.1, 0.5, 1.0, and 2.0 mol%) to examine its effect on luminescence properties. luminescence intensity enhanced as the Sm content increased to 0.5 mol% before decreasing at higher concentrations due to the concentration quenching effect. Additionally, fluorescence decay time measurements indicated a reduction in lifetime with increasing SM3+ content, attributed to energy transfer via cross-relaxation mechanisms. The CIE diagram confirmed that Sm2O3-doped glass emitted orange light. These findings suggest that SM3+-doped borate glasses hold promise for applications in orange-emitting photonic devices.
