Fine Sr2CeO4 particles of a blue emission phosphor have been synthesized using a chemical co-precipitation technique, and the textual and optical properties were compared with the one synthesized by the conventional solid-state reaction method. Mean particle size of the prepared Sr2CeO4 fine particles was smaller than that given by the sample prepared from the solid-state reaction method. However, photoluminescence intensity was maintained in spite that it usually decreases with the particle size reduction.
