CaMoO4 nanoparticles were successfully synthesized by a molten salt method at a temperature as low as 270 degrees C. The as-prepared powders, characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM), exhibited a pure CaMoO4 phase about 70 nm in particle size and uniform nearly-spherical particle shape. The room temperature luminescent spectra were performed on a Fluorolog-3 spectrofluorometer; the powders exhibited green emission peaks of 508 nm. The molten salt medium could speed up the diffusion rates of the reaction ions, and thus decrease greatly the synthesis temperature of CaMoO4 nanoparticles.
