Synthesis and characterization of ZnO-CuO nanocomposites

摘要

In this work, we present the synthesis and characterization of nanoparticles suitable for semiconductor applications using a simple and economical sol-gel process. ZnO-CuO is the potential material because of its high thermal stability and low cost. Properties of the ZnO-CuO nanocomposites are size dependent and when the particle size is reduced to the nanometer scales it shows some novel properties. Sol-Gel method is a good method to synthesis ultrafine metallic oxide nanocomposites and has been widely used for preparing nanoparticles at very low temperatures. Nano- structured ZnO-CuO has been characterized by using various techniques like XRD, SEM, and DSC-TGA. The phase transformation was investigated by an X-ray diffractometer (XRD). The microstructure was characterized by a scanning electron microscope (SEM). DSC-TGA analysis was used to investigate the thermal properties of the material.
