Abstract

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.

银、镧激活多孔玻璃复合材料的发光性能

摘要

合成了基于银和镧激活的高硅纳米多孔玻璃基质的复合材料（CM）。已确定，根据成分，由于存在孤立的 Ag ^{+ -}离子、Ag ⁺ –Ag ⁺配对中心，CM 样品在紫外、紫蓝色、绿色、红色和红外光谱范围内表现出发光，银的分子簇（MC）和纳米粒子（NP），以及La ₂ O ₃中的氧空位，以及各种硅缺陷中心。
