Optical and morphological properties of Ce-doped TiO2–MoO3 ceramic matrix

This study involves the production of a yellow ceramic pigment and examines the influence of the addition of Ce2O3 to a TiO2–MoO3 matrix processed by solid state reactions in a calcination step at 1200 °C. The presence of Ce+3 ions in the matrix leads to a decrease in the band gap value, intensifying the yellow color of the pigment. The absorbance spectra show light absorption in the visible region at a wavelength in the range of yellow color. The system under study results in a yellow pigment with a more intense color than that of the matrix.
