摘要

在AgNO3存在下，将多孔硅酸盐玻璃基体浸渍在酸化的Bi(NO3)3·5H2O水盐溶液中，在650℃或870℃热处理，合成了可变银含量的含铋复合材料（CMs），并对其发光性能进行了研究。由于各种活性中心（Bi3+, Bi2+， Bi+离子，铋二聚体，与硅相关的铋活性中心（BACs）， Ag+离子，银纳米团簇，硅缺氧中心，=Si0中心）的存在，合成的材料在220-900 nm的宽光谱范围内表现出光致发光。

Luminescent Properties of Composites Based on Silicate Porous Glasses Activated with Bismuth and Silver

Bismuth-containing composite materials (CMs) with variable silver content are synthesized by impregnating porous silicate glass matrices in acidified aqueous-salt solutions of Bi(NO₃)₃·5H₂O in the presence of AgNO₃ with their subsequent heat treatment at 650 or 870°C and their luminescent properties are studied. The synthesized materials exhibit photoluminescence in a wide spectral range (220–900 nm) due to the presence of various active centers (Bi³⁺, Bi²⁺, Bi⁺ ions, bismuth dimers, bismuth active centers (BACs) associated with silicon, Ag⁺ ions, silver nanoclusters, silicon oxygen-deficient centers, =Si⁰ centers).
