Description 51-56
Sonochemical synthesis and optical properties of the ZnO- Bi₂O₃ nanocomposite materials have been reported. SEM and TEM studies show the morphology to be stelliform dendrite. The sonication time appears to be a critical parameter for shape determination. Also, the presence of Bi³⁺ is vital to the formation of the stelliform dentrites. UV and photoluminescence spectra at room temperature of the products show that the synthesized materials possess good optical properties. The mechanism of the stelliform dendrite growth has also been discussed.
