摘要

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.
