The novel phosphors of doped with , , and were synthesized by solid-state reaction, and their luminescence properties were investigated. The phosphors show pure three-basal-color (red-green-blue) luminescence in the CIE1931 chromaticity diagram, and it was observed that the concentration quenching was dependent on the different dopant contents. This series of phosphate-based phosphors shows higher thermally stable luminescence, which was found to be better than commercially available phosphor at temperatures higher than . Considering the situation of high color-rendering index and chemical stability, we have demonstrated that are potentially useful new scintillation materials for white-light-emitting diodes.
