Abstract
Uniformly dispersed copper oxide nanoparticles in poly(vinyl alcohol) (CuO- PVA) have been synthesized by the sonochemical method. The properties of th e as-prepared composite material are characterized by XRD, DSC, thermogravi metric analysis (TGA), TEM, and diffuse reflection spectroscopy (DRS). A ba nd gap of 2.1 eV is estimated from DRS measurements. The controlled crystal growth of copper oxide has been studied by using the as-prepared CuO-PVA c omposite as seed for the crystal growth of copper oxide. Well-shaped crysta ls of 1 mum in length were grown.
