摘要
A new blue emitting phosphor, Eu0.5Zr2(PO4)(3), was synthesized for the first time by the solid-state reaction method. The sample developed in the present study has a stable NASICON-type rhombohedral structure, which consists of a three-dimensional network formed by PO4 tetrahedra sharing corners with ZrO6 octahedra in a single phase with high crystallinity. The photoluminescent emission spectrum shows typical emission from 4f(6)5d(1) to 47 of Eu2+, although the improvement of the luminescent property will be necessary by optimization of the preparation process and the modification of the particle morphology.
