Abstract

A new blue emitting phosphor, Eu 0.5Zr 2(PO 4) 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 PO 4 tetrahedra sharing corners with ZrO 6 octahedra in a single phase with high crystallinity. The photoluminescent emission spectrum shows typical emission from 4f 65d 1 to 4f 7 of Eu 2+, although the improvement of the luminescent property will be necessary by optimization of the preparation process and the modification of the particle morphology.
