Photoluminophores Based on Porous Glasses Coactivated by Cu2+ and Y3+: Synthesis and Spectral Properties
Composite materials (CMs) based on matrices of high-silica porous glasses activated by Cu2+ and Y3+ ions are synthesized. The influence of the composition of composites (concentration and ratio of copper and yttrium introduced) and the temperature of their heat treatment (in the range of 50–870°C) on their spectral properties is studied. Examining samples using optical and IR spectroscopy reveals absorption bands related to Cu2+ ions and caused by vibrations of the Y–O bonds in Y2O3. It is established that, depending on the synthesis conditions, the obtained materials possess UV, blue-green, and IR luminescence due to the presence of various active centers (defects and oxygen vacancies in CuO, Cu2+ ions, radicals , and F centers in Y2O3, =Si0 centers, E' centers (O3≡\({\text{Si}} \cdot \)), neutral oxygen vacancies (O3≡Si–Si≡O3), and nonbridging oxygen defect centers in the silica matrix of glass.
