Preparation of cerium hydroxycarbonate by a surfactant-assisted route Original Research Article

Cerium hydroxycarbonate (CeOHCO3) with shuttle-like morphology has been conveniently synthesized at 90 °C from aqueous solution in the presence of polyvinylpyrrolidone (PVP). The products were characterized by X-ray diffraction, transmission electron microscopy and photoluminescent (PL) techniques. The as-prepared CeOHCO3 was found to have a PL emission at about 347 nm. Experimental conditions as well as the role of PVP played in the reaction were also explored.
