Abstract

Composite materials (CMs) based on porous glass matrices activated by yttrium in the presence of copper or bismuth are synthesized. It is established that, depending on the composition, the CM samples exhibit UV, blue-green, red, and infrared luminescence due to the presence of various centers, including Bi³⁺ and Cu⁺ ions, F centers in Y₂O₃, and molecular ions \({\text{O}}_{3}^{{ - 2}}\) associated with cation vacancies Y³⁺.

铜或铋存在下钇激活的纳米结构复合玻璃材料的光谱特性

摘要

合成了基于在铜或铋存在下由钇激活的多孔玻璃基质的复合材料（CM）。已确定，根据组成，CM 样品由于存在各种中心（包括 Bi ³⁺和 Cu ^+离子、Y ₂ O ₃中的 F 中心、和与阳离子空位 Y ³⁺相关的分子离子\({\text{O}}_{3}^{{ - 2}}\)。
