The doping of a host glass with rare-earth ions is quite interesting when investigating their wide applications in several fields, such as laser and optical fibers. In this study, the glass medium had a composition of (70 − x) P₂O₅–10Bi₂O₃–10Na₂O–10Gd₂O₃–xSm₂O₃ with x = 0, 0.05, 0.1, 0.5, 1.0, 3.0 mol% and were fabricated using melt-quenching method. The optical properties of Sm³⁺-doped samples with different Sm³⁺ concentrations were determined by measuring the absorption and luminescence spectra in the visible light region. Both the direct and the indirect bandgap energies were slightly decreased after doping with Sm³⁺ ions. The maximum experimental oscillator strength was 3.65 × 10^–6 for the band transition ⁶H_5/2 → ⁶F_7/2 over glass PBNaGSm5. The Judd–Ofelt parameters were applied to evaluate the properties of glass samples. The highest emission intensity was located in the orange range with a wavelength of 597 nm under an excitation wavelength of 401 nm. An obvious decrease in the lifetime was observed at higher Sm³⁺ ion concentrations.

在研究玻璃在诸如激光和光纤等多个领域的广泛应用时，用稀土离子掺杂玻璃是非常有趣的。在这项研究中，玻璃介质的成分为（70 − x）P ₂ O ₅ –10Bi ₂ O ₃ –10Na ₂ O–10Gd ₂ O ₃ –xSm ₂ O _3，其中x  = 0、0.05、0.1、0.5 ，用熔融淬火法制得1.0、3.0mol％的H 2 O 3。不同Sm ³⁺掺杂Sm ^3+的样品的光学性质通过测量可见光区域的吸收光谱和发光光谱确定浓度。掺杂Sm ³⁺离子后，直接和间接带隙能均略有下降。在玻璃PBNaGSm5上的频带跃迁⁶ H _5/2  →  ⁶ F _7/2，最大实验振荡器强度为3.65×10 ^–6。使用Judd–Ofelt参数评估玻璃样品的性能。在401nm的激发波长下，最高发射强度位于橙色范围内，波长为597nm。在较高的Sm ³⁺离子浓度下，观察到寿命明显降低。
