The growth of Ce1−xPrxO2 single crystals (xsimilar, equals0.05) has been investigated in connection with a systematic research work o n rare earth based red pigments. Ce1−xPrxO2 crystals have been grown by spontaneous nucleation during slow cooling of a high temperature solution using PbF2-Pb3P2O8-NaF or Na2B4O7-NaF as solvents. X-ray diffraction, chemical analysis and optical study were performed on the obtained single crystals. Stabilization of Pr4+ in cerium oxide accounted for the observed red color.
