Composite materials (CMs) were synthesized on the basis of nanoporous silicate glasses (PGs) with small additives of P2O5 and fluoride ions doped by silver bromide in the presence or in the absence of cerium or erbium. The obtained CMs were characterized by a complex of methods (X-ray powder diffraction (XRD) technique, energy-dispersive X-ray spectroscopy, and UV-Vis-NIR spectroscopy). According to the XRD data, the CMs contain the cubic phases of AgBr (No. 01-071-3754) and KBr (No. 01-089-3620). It was foundby energy-dispersive X-ray spectroscopy that the concentrations of oxygen, silicon, potassium, and silver are uniformly distributed over the whole thickness of the samples. The optical properties of the CMs depending on their composition and heat treatment temperature (in the range from 120 to 870 °C) were compared. The absorption bands characteristic of molecular clusters and nanoparticles of silver, as well as cerium and erbium ions were revealed.

溴化银和Ce3+或Er3+离子掺杂复合材料的相组成和光学性能

在纳米多孔硅酸盐玻璃 (PGs) 的基础上合成了复合材料 (CMs)，在存在或不存在铈或铒的情况下，通过溴化银掺杂 P2O5 和氟离子的少量添加剂。获得的 CM 通过多种方法（X 射线粉末衍射 (XRD) 技术、能量色散 X 射线光谱和 UV-Vis-NIR 光谱）进行表征。根据 XRD 数据，CM 包含立方相 AgBr（编号 01-071-3754）和 KBr（编号 01-089-3620）。通过能量色散X射线光谱发现，氧、硅、钾和银的浓度在样品的整个厚度上均匀分布。CMs 的光学特性取决于它们的成分和热处理温度（在 120 到 870 °C 的范围内）。
