摘要：

CdO nanoparticles with different sizes were synthesized by a simple thermal decomposition reaction of the precursor CdCO3, which was synthesized by room-temperature grinding reaction between Cd(CH3COO)(2)center dot 2H(2)O and Na2CO3. Composition, structure and morphology of the products were analyzed and characterized by XRD, TG and FUR spectra. Formation of CdO nanoparticles was thought that nucleation rate of the reactive system was far excess growth rate of particle. Optical properties of the products were recorded, and the UV-vis spectra exhibited the distinct blue shift in comparison with them of the bulk CdO, which was because that the quantum confinement effect of the products could be larger than the Coulomb effect. PL spectra of the products showed the emission bands around 520 and 720 nm respectively, which attributed to the quantum size effect and structural defects in the crystals.
