摘要

摘要以银和镧活化的高硅纳米多孔玻璃为基质合成了复合材料（CMs）。结果表明，由于存在孤立的 Ag+离子、Ag+-Ag+ 配对中心、银的分子团（MC）和纳米颗粒（NP）、La2O3 中的氧空位以及各种硅缺陷中心，根据组成的不同，CM 样品可在紫外、紫蓝、绿、红和红外光谱范围内发光。

Luminescent Properties of Composite Materials Based on Porous Glasses Activated by Silver and Lanthanum

Composite materials (CMs) based on matrices of high-silica nanoporous glasses activated by silver and lanthanum are synthesized. It is established that, depending on the composition, the CM samples exhibit luminescence in the UV, violet-blue, green, red, and infrared spectral ranges due to the presence of isolated Ag⁺-ions, Ag⁺–Ag⁺ paired centers, molecular clusters (MCs) and nanoparticles (NPs) of silver, and oxygen vacancies in La₂O₃, together with various silicon defect centers.
