Abstract

Composite materials (CMs) containing Tb³⁺ ions and silver bromide, based on matrices of high-silica nanoporous glasses, are synthesized. It is found that the samples, depending on the conditions of their synthesis, possess UV (λ_lum = 310 nm at λ_exc = 266 nm) and blue-green (λ_lum = 400–545 nm at λ_exc = 316–375 nm) luminescence due to the presence of silicon defect centers and the presence of paired Ag⁺–Ag⁺ centers, Tb³⁺ ions, and isolated Ag⁺ ions. The concentration distribution of the elements over the thickness of the samples is established by the method of energy-dispersive X-ray spectroscopy.

Tb 3+离子和AgBr活化的纳米多孔硅酸盐玻璃基复合材料的发光性能

摘要

基于高二氧化硅纳米多孔玻璃的基质，合成了包含Tb ³⁺离子和溴化银的复合材料（CMs）。据发现，样品，这取决于它们的合成的条件下，具有UV（λ _LUM = 310nm的在λ _EXC = 266纳米）和蓝绿色（λ _LUM = 400-545纳米在λ _EXC = 316-375纳米）由于存在硅缺陷中心以及成对的Ag ⁺ -Ag ⁺中心，Tb ³⁺离子和孤立的A​​g ⁺离子而导致发光。元素在样品厚度上的浓度分布是通过能量色散X射线光谱法确定的。
