合成了Ce1-xZrxBiyO2-y/2固溶体作为新型无机黄色颜料，并研究了其作为生态材料的显色性能。虽然Ce1-xZrxBiyO2-y/2颜料的光学吸收边取决于其组成，但所有样品都能有效吸收500 nm以下的紫外线和可见光。在x = 0.37和y = 0.20时获得最有效的黄色色调。通过比较Ce0.43Zr0.37Bi0.20O1.9和Ce0.43Zr0.37La0.20O1.9的颜色，阐明了Bi3+在CeO2-ZrO2晶格中存在的重要性。Ce1-xZrxBiyO2-y/2固溶体的表征表明，它们有潜力成为油漆、油墨、塑料和陶瓷的替代黄色着色剂。由于它们是由无毒和安全的元素组成的，所以它们是惰性和安全的，对人体没有副作用。(C) 2007 Elsevier B.V.版权所有
Ce1-xZrxBiyO2-y/2 solid solutions were synthesized as new inorganic yellow pigments and their color properties have been investigated as possible ecological materials. Although the optical absorption edge of the Ce1-xZrxBiyO2-y/2 pigments depends on their composition, all samples absorb the ultraviolet and the visible light under 500 nm efficiently. As a result, the pigments show a brilliant yellow color, and the most effective yellow hue was obtained at x = 0.37 and y = 0.20. The importance of the presence of Bi3+ in the CeO2-ZrO2 lattice has been elucidated by comparing the color of Ce0.43Zr0.37Bi0.20O1.9 with that of Ce0.43Zr0.37La0.20O1.9. Characterization of the Ce1-xZrxBiyO2-y/2 solid solutions suggests that they have a potential to be altemative yellow colorants for paints, inks, plastics, and ceramics. Since they are composed of non-toxic and safe elements, they would be inert and safe and exhibit no side effects in the human body. (C) 2007 Elsevier B.V. All rights reserved.
