Abstract

Composite materials based on matrices of high-silica nanoporous glasses activated with bismuth and cerium ions are synthesized. It is found that the samples, depending on the conditions of their synthesis, exhibit blue-green luminescence (λ_lum = 416–539 nm at λ_exc = 357–410 nm) due to the presence of Bi³⁺ and Ce³⁺ ions. Characteristic vibrations of CeO₂ and α-Bi₂O₃ are identified in the composite materials by IR spectroscopy.

基于铋和铈离子活化的纳米多孔高硅玻璃复合材料的光谱发光性能

摘要

合成了基于铋和铈离子活化的高硅纳米多孔玻璃基质的复合材料。据发现，样品，这取决于它们的合成的条件下，显示出蓝绿色发光（λ _LUM = 416-539纳米在λ _EXC = 357-410纳米）由于Bi的存在³⁺和Ce ³⁺离子. CeO ₂和α-Bi ₂ O ₃在复合材料中的特征振动通过红外光谱确定。
