As compared with red sulfide low voltage electroluminescent phosphor Zn1-xCdxS (x=0˜1.0), titanate substrate has a good chemical stability, and the phosphor obtained by doping rare earth luminescent center ions, such as CaTiO3, has a better color purity. The coordinates of red color of Pr3+ excited by photoluminescence and cathode ray are: x=0.680, y=0.311, which are very close to that of the ideal red according to NTSC color gamut. Considering the material stability and luminous colors, the titanate substrate phosphor activated by rare earth ion is expected to replace red sulfide phosphor Zn1-xCdxS and become a new generation of non-toxic, highly stable red FED phosphor material. Accordingly, it is the goal of researchers for further improving the luminescent properties of this material.
