A novel red-emitting phosphor CaAl12-x-y(PO4)0.1O18.85: xMn4+, yMg2+ was synthesized by a high-temperature solid-state method. The crystal structure and luminescence properties of the samples were characterized by X-ray diffraction, scanning electron microscopy and fluorescence spectroscopy. The results show that the synthesized phosphor has a hexagonal crystal structure with the space group of P63/mmc. The optimal doping amounts of Mn4+ and Mg2+ are x of 0.01 and y of 0.1, respectively. Under excitation at 396 nm, CaAl11.89(PO4)0.1O18.85: 0.01Mn4+, 0.1Mg2+ phosphor shows the maximum red light emission at 654 nm, corresponding to 2E→4A2g transition of Mn4+. The luminescence intensity and lifetime of phosphor are improved due to the co-doping with Mg2+ charge compensator. The absolute quantum efficiency of phosphor is 60%, the fluorescence lifetime is 0.97 ms, the color coordinate is in the deep-red region, and the color purity is 97%. The luminescence intensity is still 60% of the initial intensity when the temperature increases to 413K, indicating that this red phosphor with a superior thermal stability is a novel red luminescent material with broad application prospects.
