CeO2-ZrO2-Bi2O3 solid solutions have been synthesized by a citrate complex route. The resulting colored materials have been characterized as potential environment-friendly pigments. The yellow hue of the pigment was significantly enhanced by the introduction of zirconium and bismuth into the CeO2 lattice, which produces intrinsic strain and a hybrid orbital of Bi-6s and 02,, respectively. The yellow pigments obtained have been found to be effective alternatives to the conventional toxic colored materials.
