| Abstract: | In this work, the photoluminescent material SrAl2O4: Eu2+ was prepared by solid-state reactionat high temperature in reducing atmosphere- Activated carbon powder was used as reductant and SrCO3,Al2O3 and Eu2O3 as raw material. Effects of factors such as addition of Eu2+ and reductant, sintering temperature, duration of constant temperature and temperature-lowering method on phosphorescent brightness and lasting time of RE phosphor were studied. The synthetic material compositions, excitation and emission spectrum of phosphor were tested. |
