Synthesis of an Environmentally Friendly and Nontoxic New Pigment Based on Rare Earth Phosphate
A new inorganic pigment based on rare earth phosphate has been synthesized with the goal of preparing ecologically and environmentally friendly specific pigments. A yellow–green pigment that consists of nontoxic elements was obtained by doping calcium ions into the cerium orthophosphate lattice. Characterizations using XRD, UV–vis spectroscopy, and colorimetric assessment revealed that the formation of a Ca-doped CePO<SUB>4</SUB> solid solution was responsible for the appearance of the color.
