The influence of short thermal treatment on structure, morphology and optical properties of Er and Pr doped ceria pigments: Comparative study
Potential non-toxic pink and red ceramic pigments based on CeO2 were successfully synthesized by self-propagating room temperature method and thermally treated at 600, 900 and 1200 °C for 15 min. The structure, morphology and optical properties, as well as thermal stability of Ce1-xErxO2-δ and Ce1-x...
