| Abstract: | CuO nanoparticles were prepared by a laser heating gas-evaporation method, with 150W CW CO2 laser as the light source and Cu(Ac)2·2H2O as the target. The effects of process parameters on nanoparticles were studied. XRD, ED and TEM were used to characterize the samples. The formation mechanism of Cu/O nanoparticles was preliminarily discussed. The experimental results show that the process parameters such as laser power density, reaction pressure, the sorts and rate of airflow etc, effect the sizes and crystal system of nanoparticles. In inert gases, the products are Cu and Cu2O, the diameter of nanoparticles is between 10 and 30nm; In oxygen, the products are Cu ,Cu2O and CuO, the diameter of nanoparticles is between 10 and 50nm. |
