Abstract

New phosphates Sr₈(Zn_1–xMn_x)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。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
