Photoluminescent properties of Eu-doped ZnLiNbO₄

In this study, fluorescent Eu 3+ -doped ZnLiNbO 4 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 ZnLiNbO 4 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 ( 7 F 0 → 5 D 2 ), and the main emission band was at 615 nm ( 5 D 0 → 7 F 2 ), 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.
