摘要：A kind of CoxR1-xAl2O4 (R=Zn, Mg, x=0.8 similar to 1.0) cobalt blue pigment suitable for luminophor of color televisions was synthesized successfully by using the chemical coprecipitation method. Compared with CoAl2O4 reflectivity, the increase of reflectivity of CoxR1-xAl2O4 is 18.2% at 450nm and -5% at 600nm respectively. Through discussing some affecting factors on this kind of pigment such as doping cation type, doping content and Co2+ content, a conclusion can be drawn that the mechanism of reflectivity properties alteration of complex cobalt blue pigments caused by doping cations Zn2+, Mg2+ is Co(2+)3d electronic energy level cleavage due to lattice distortion. The lower limit value of x of Zn2+, Mg2+ is 0.85 and 0.8 respectively.
