摘要

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。

Structural Features of Strontiowhitlockite-Based Luminophores

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.
