摘要

In this work, Sm3+ doped strontium-magnesium aluminosilicate glasses were made by traditional melting method. The influence of the Al2O3/SiO2 ratio on the luminescence properties of Sm3+ ions was investigated using XRD, Raman, spectrophotometry, and Judd–Ofelt theory, respectively. As the Al2O3 concentration increases, the number of Al-O bonds in the glass network also rises, significantly improving the absorption of Sm3+ ions, which in turn improves their luminescent performance. Under the excitation of 405 nm, the emission peak is mainly located near 602 nm. When the Al2O3/SiO2 ratio is 0.6, the glass exhibits the highest luminescence intensity. The effective bandwidth of the A0.6 glass sample at the 4G5/2 → 6H7/2 transition is 18.52 nm, with an emission cross-section of 7.13 × 10⁻22 cm2. The experimental results show that the glass samples have excellent orange light emission properties, and these samples have potential application prospects in the field of color development.
