Preparation and Characterization of Amorphous Ce_(1-x)Zr_xW_2O_8 Fine Particles for Environmental-friendly Yellow Pigments

摘要

New inorganic pigments based on amorphous cerium tungstate have been synthesized with the goal of preparing ecologically and environmental-friendly specific pigments.These pigments consist of all non-toxic elements and show brilliant yellow color.The reason for the color change was attributed to the modification of the O_(2p)-Ce_(4f)and the O_(2p)-W_(5d)double charge transfer transitions with the Zr doping.
