| 摘 要： | 采用化学共沉淀法成功地制备出适用于彩电显象管内荧光体着色的ＣｏｘＲ１－ｘＡｌ２Ｏ４（Ｒ＝Ｚｎ、 Ｍｇ， ｘ＝０．８～１．０）钴蓝颜料： ４５０ｎｍ波长处反射率最大提高１８．２％， ６００ｎｍ处反射率最大降低５％。通过对该颜料反射率的影响因素，如掺杂离子类型、掺杂浓度和Ｃｏ２＋离子浓度的探讨，结论如下：Ｚｎ２＋、Ｍｇ２＋改变钴蓝颜料反射性能的作用机理为晶格畸变引起Ｃｏ２＋３ｄ轨道电子能级分裂程度的变化；对于掺杂离子Ｚｎ２＋、Ｍｇ２＋，ｘ下限值分别约为０．８５和０．８．

| 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 |
