ZnO-Bi2O3 nanocomposite particles with three-level fractal structure have been synthesized by doping Bi3+ into ZnO under ultrasonic irradiation.The composition of the product was defined by XRD and XPS.Images of TEM and SEM revealed that the sonication time appeared to be a critical parameter for the shape determination of the products.Also the doping of Bi3+ acted as a structure-directing agent in the formation of the fractal dentrite particles.Meanwhile,the formation mechanism of the fractal dendrite growth has been discussed.The UV-Vis and Photoluminescence spectra at room temperature of the products were investigated and the results indicate that the synthesized materials possess optical properties.

Key words: tree warty;sonication;doping, fractal, complex nano-oxides
