Abstract

New phosphates Sr8(Zn1–xMnx)La(PO4)7 are obtained by the solid phase synthesis. A continuous series of solid solutions is shown to form. All synthesized compounds crystallize in the strontiowhitlockite structure type with space group \(R\bar{3}m\). Structural parameters are refined by the Rietveld method. The luminescent properties are studied, and the relationship with the crystal structural features is determined. Samples exhibit stable red-orange luminescence. The sample with x = 0.5 has the highest photoluminescence intensity.

基于锶白锁石的发光体的结构特征
摘要 通过固相合成法获得了新型磷酸盐 Sr8(Zn1-xMnx)La(PO4)7 。结果表明形成了一系列连续的固溶体。所有合成的化合物都以空间群(R/bar{3}m/)的锶白锁石结构类型结晶。结构参数是用里特维尔德法精制的。对发光特性进行了研究,并确定了其与晶体结构特征之间的关系。样品呈现出稳定的橘红色发光。x = 0.5 的样品具有最高的光致发光强度。
