AbstractCeramic pigments based on cerium oxide were synthesized by self–propagating room temperature method and their color properties were assessed from the viewpoint of potential environmentally nontoxic pink pigments. Thermal stabilities of the pigments were examined at 600, 900 and 1200 ºC. According to X–ray powder diffraction and Raman spectroscopy results, all obtained pigments were single–phase solid solutions of cerium oxide, independent of the concentration of dopants. The X–ray analysis showed that the crystallites were of nanometric dimensions, as recorded and by transmission electron microscopy analysis. Color characteristics of solid solutions, which depended on concentracion erbium ions and calcination temperature, and their position in the chromaticity diagram were studied by ultraviolet–visible spectrophotometry, which confirmed potential application of environmentally friendly pigments of desired color. The color efficiency of pigments was also evaluated by colorimetric analysis.
