摘要

在硅基多孔阳极氧化铝中，以钇、铝和硝酸铽为原料，采用共沉淀法合成了不同铽浓度的复合材料。研究了这些结构的光致发光。结果表明，在铽浓度为0.1 mol.%的溶液中得到的钇铝复合材料在绿色范围内的光致发光最强烈。随着铽浓度的进一步增加，与铽相关的光致发光强度降低。

Photoluminescence of the yttrium aluminum composites doped with various concentrations of terbium

The composites with various terbium concentrations are synthesized in the silicon-based porous anodic alumina by the coprecipitation method from solutions of yttrium, aluminum and terbium nitrates. The photoluminescence of these structures is investigated. It is found that the yttrium aluminum composite obtained from the solution with terbium concentration 0.1 mol.% demonstrates the most intensive photoluminescence in the green range. The terbium related photoluminescence intensity decreases with a further increase in the concentration of terbium.
