英文摘要	Red phosphors MgxCa1-xTiO3:Eu3+ (0The crystalline structure and morphology of the as-prepared samples were confirmed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The luminescence property was measured using photoluminescence excitation and photoluminescence emission spectra. Results showed that spherical particles appeared in the phosphor bodies and size of the phosphor particles were uniformly distributed in the range of 600-800 nm when the Mg2+ concentration was about 40 mol.%. It could readily be seen that the strongest PL emission was located at 617 nm monitored at 398 nm, which well matched with the near ultraviolet (NUV, 395-400 nm) GaN-LEDs. More importantly, PL emission intensity (617 nm) of phosphor Mg0.4Ca0.6TiO3:0.03Eu(3+) was 4.26 times of that of phosphor CaTiO3:0.03Eu(3+). Based on these results, it implied that the PL intensity of phosphorCaTiO(3):0.03Eu(3+) could be significantly enhanced by introducing Mg2+ into CaTiO3 host lattices and the phosphor Mg0.4Ca0.6TiO3:0.03Eu(3+) might be the promising red-emitting phosphor in making tricolor phosphor converted white-LEDs.
