摘要
Abstract
A kind of CoxR1-xAl2O4(R=Zn、Mg，x=0.81.0)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 Co2+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关键词
