Abstract As a key material, the phosphor plays an important role in high-quality lighting with high color rendering and low light attenuation, as well as in backlight source of wide color gamut display. With the development requirements for the light color quality, the performance of phosphors is critical. Therefore, it is urgent to design and develop new phosphate phosphors with excellent luminescent properties. The rare earth doped phosphate phosphor shows many advantages such as low synthesis temperature, high quantum efficiency and good chemical and physical stability. The new phosphors with excellent luminescent properties had been developed by designing the crystal structure of the matrix solid solution, doping activator ion, morphology control and designing core-shell structure. This review provides elaborate descriptions about the structure of several phosphate matrixes, the ways of improving the photoluminescence of the rare-earth doped phosphate phosphors, and the discovery of the recent work. We then pay attention to the problems confronting the current state of the rare-earth doped phosphate phosphors. It is expected to provide theoretical guidance for the design, preparation and practical application of more novel phosphates with excellent luminescence and secondary performance for luminescence and lighting display in this paper.
