摘要：

A blue-emitting phosphor powder, Sr2CeO4, was synthesized after heat-treatment to carbonate and oxalate precursors, which were obtained by co-precipitation reactions with respective ammonium compounds as precipitants. The phase formation and chemical purity of Sr2CeO4 powders were studied on XRD, TGA and XPS techniques. Their fluorescent performances were investigated and compared. The photoluminescence emission spectra for the phosphor prepared from respective precursors are similar, having a broad band with the peak at about 470 nm. However, their fluorescent intensities are different after heat-treatment at same conditions. The optimum condition to achieve superior Sr2CeO4 phosphor is confirmed.
