Abstract:In this paper, Y₂O₃:Eu red film photoluminescence material and device were prepared by sol-gel method, using SnO₂ as nesa coating and SrTiO₃ as ceramic substrate. The prepared material and device were characterized by XRD, SEM,fluorecence spectrum. Effects of Eu³⁺ doping content, sintering temperature and Eu³⁺ doping amount on matrerial's luminous property was investigated.The results showed that the optimum doping content of Eu³⁺ was 8mol%, the optimum sintering temperature was 900℃ for 1h, and the main emission peak of material appeared at 614nm, which was attributed to typical 5D0-7F2 electric dipole transitions of Eu³⁺.

Keywords:film, photoluminescence material, sol-gel method
