摘　　要：以固相反应法合成新型黄色颜料CaZr_(0.9)V_(0.1)O_3。利用X射线衍射仪对样品的晶体结构进行表征,借助紫外-可见-近红外分光光度计测试合成颜料的近红外反射率和颜色参数。通过能带理论和电子跃迁假说分析颜料对光的吸收机理。结果表明:CaZrO_3掺杂V后,合成颜料的近红外反射率为95.88%,颜料的带隙由3.88eV减小为3.84eV;颜料CaZr_(0.9)V_(0.1)O_3色相处在CIEL*a*b*标准的黄色区域,并且色彩饱和度由CaZrO_3颜料的10.28增加为34.97,明度由90.71增加为93.66;CaZrO_3掺杂V后,颜色变得更深更亮。A new type of yellow pigment CaZr（0.9）V（0.1）O3 was synthesized by solid state reaction method.The samples were characterized by X-ray diffraction（XRD）analysis and UV-Vis-NIR spectroscopy analysis.Energy band theory and electron transition hypothesis were used to investigate the absorption of light.The results showed that the near-infrared reflectance value was 95.88% of CaZrO3 with the doping of V5＋.The band values decreased from 3.88 eV to 3.84 eV.The brightness of pigment increased from 90.71 to 93.66 as V5＋doping.The color of pigment changed from rose pink to yellow and became deeper and brighter.
