Abstract
The formation and growth of CeOCl crystals from a Ce3+ precursor in a molten KCl-LiCl flux was investigated. The formation of CeOCl occurred through the reaction Ce3+ + Cl− + [O2−] = CeOCl, where Ce3+ came from both CeO2−x (0 < x < 0.5) and Ce2O3, and the [O2−] was the lattice oxygen. CeOCl started to form in the powder together with ceria at 400 °C under hydrogen atmosphere, and the CeOCl content was 91.3% then decreased with increasing synthesis temperature. The growth of CeOCl crystals observed by SEM images revealed that cubic CeOCl particles were formed from polyhedral flakes. Photo-Luminescence (PL) spectra showed that the violet-blue light can be emitted from synthesized powder, which suggests CeOCl can be a potential luminescence material.
