CdO nanoparticles with different sizes were synthesized by a simple thermal decomposition reaction of the precursor CdCO,which was synthesized by room-temperature grinding reaction between Cd（CHCOO）·2HO and NaCO. Composition,structure and morphology of the products were analyzed and characterized by X-ray diffraction technology,transmission electron microscopy, thermogravimetry and fourier infrared *** of CdO nanoparticles is thought that nucleation rate of the reactive system is far excess growth rate of particle. Optical properties of the products were recorded,and the ultraviolet-visible spectra exhibit the distinct blue shift in comparison with them of the bulk CdO,which is because that the quantum confinement effect of the products should be larger than the Coulomb *** spectra of the products exhibit the emission bands around 520 and 720 nm,respectively,which attributed to the quantum size effect and structural defects in the crystals.
