摘要
本文通过共沉淀法制备了Co_(1-x)Mg_xAl_2O_4(x=0 to 0.8)系复合纳米粉体。采用XRD、TG-DSC、SEM、CIE-L~*a~*b~*和UV-vis等测试技术对粉体的相组成、颗粒形貌、粒径、色度和吸光度等进行了表征。结果表明,制备的样品均为单一的尖晶石结构,置换离子成功地进入CoAl_2O_4结构中,并逐渐取代Co~(2+)离子在四面体中位置,致使晶格发生畸变,结晶度、粒径和色度发生变化。L~*a~*b~*值分析显示,合成粉体在x=0.6时,得到最大的-b~*值,表明蓝色值最大。UV-vis光谱分析表明,在530~670nm范围内存在一系列较强吸收峰,这表明蓝色的形成。同时,在480nm处的吸收峰的改变,影响色料粉体的亮度(L~*值)。
CO_(1-x)Mg_xAl_2O_4(x ranges from 0 to 0.8) nano-pigments were prepared by Co-precipitation method and characterized by means of TG-DSC,XRD,SEM,colorimetry and UV-vis.The XRD patterns showed that the obtained samples have single phase cubic spinel structure.Metal ions were incorporated within the CoAl_2O_4 structure and gradually replaced the Co~(2+) ions in the tetrahedral positions,which yielded a crystal lattice distortion and made crystallite,the particle size and color tone changed.The chromatic data revealed that the most b* value in negative occurs for x=0.6,indicating a highest blue intensity.A continuously strong absorption is depicted in the range 430-670 nm,which revealed the formation of a blue color.Meanwhile,the absorption bands around 480 nm have a great influence on the lightness of pigments.
