Phosphors Ca4(PO4)2O:Ce3+/Li+,Eu2+ were prepared by solid state reaction successfully, and characterized by X-ray dif-fraction, UV-Vis spectrometer and photoluminescence spectrometry. The as-prepared phosphors exhibited strong absorption in the UV-visible region and dual-emission bands centered at approximately 460 and 630 nm. Energy transfer from Ce3+ to Eu2+ was also observed. By varying the excitation wavelength, these new phosphors exhibited tunable emissions from blue to white and then to yel-low, making them potential candidates as UV-convertible phosphors for white light emitting diodes.
