Preparation and Characterisation of ZnO - SiO2 and Bi2O3 – CuO Nanocomposites
In the present work, ZnO - SiO2 and Bi2O3– CuO nanocomposites have been prepared by sol gel with alternate precursors existing in literature. They are characterised by XRD, SEM,UV, FTIR and photoluminescence spectra .The XRD results indicate a crystallite size of approximately 80 nm for both nanoc...
