Characteristics of Sr2CeO4 Powder Phosphor Prepared by Combustion Route


Article Preview

The precursor powder of Sr2CeO4 was prepared from a nitrate starting solution by a combustion route with urea as a fuel. Sintering the precursor powder at different temperatures for 6h, a blue-white emission phosphor was synthesized. The microstructure and photoluminescence studies of Sr2CeO4 compound are reported. The particle sizes of the powder phosphor are around 0.5-2 µm when heat treated between 9500C to 11500C and the emission spectrum exhibits a broad band maximum at about 470 nm. The chemical purity and photoluminescence intensity of Sr2CeO4 powder phosphor strongly depend on the post-heat-treated temperature.
