摘要：

This work reports on the preparation of Sr2CeO4 blue phosphor with fine particles by using a powder multi-component precursor via combustion method, varying the fuel. Citric acid or glycine as fuels lead to the formation of different phase mixture. After heating under 950degreesC both different phase mixtures result on a material that the mainly phase is the Sr2CeO4. White blue luminescence is only observed for these samples after thermal treatment and both of them present similar emission and excitation spectra that are characteristics of Sr2CeO4 phase. Therefore, the combustion method is adequate for blue phosphor preparation.
