During the process of developing commercial chips, the phosphors with single broadband emission are indispensable. In this report, a new ternary phosphate phosphor Na3Ba2Ca(PO4)(3):Eu2+ has been successfully synthesized by the high-temperature solid-state reaction (HSSR) method, which shows broad emitting band in the range of 350-600 nm centered at 436 nm (FWHM similar to 72.3 nm). The crystal structure of the Na3Ba2Ca(PO4)(3) and Eu2+ doped Na3Ba2Ca(PO4)(3) were determined by the Rietveld method, indicating the trigonal system with P31c space group. The selective two-site occupancy tendency o...
