Photoluminescent properties of Eu-doped ZnLiNbO4

In this study, fluorescent Eu3+-doped ZnLiNbO4 materials were prepared via a vibrating milled solid-state reaction method. The objective was to develop new fluorescent oxide materials and study their fluorescent properties. The ZnLiNbO4 tetragonal spinel structure was formed with a single phase at a sintering temperature of 800 ?C and with a regular shape at 1000 ?C. The main exciton band was at 466 nm (7F0???5D2), and the main emission band was at 615 nm (5D0???7F2), which was an orange?red light band. The emission intensity was approximately 5% when the doping concentration reached 7%. The decay time was 2.96 ms.
