The nanocomposite powder of rare earth-doped CuO were prepared by the stearic gel method and characterized by means of X-ray (XRD) and, transmission electron microscopy (TEM) and, scanning electron microscope (SEM) and Infrared Radiation (IR). Microscopic investigation of the nanopowder was measured by Atomic Force Microscope (AFM). The results showed that the grain sizes are in the order of nanometers, approximately 10 nm, 12 nm, 22 nm, 32 nm and 40 nm for the nanopowder deposited at 600oC, 650oC, 700 oC, 750 oC and 800 oC, respectively. The grains grew up with the increase of sintering temperature. There were some agglomeration and self-assembly phenomenon in the particles. Based on the IR results, it clearly showed that the vibration kurtosis was changed with the different sintering temperature.
