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