Abstract

Nanocrystalline ZnO thin films with different morphology were grown on silicon substrate by sol-gel process using different zinc acetate sol concentrations. These films were characterized by high resolution XRD, SEM, EDS, photoluminescence (PL) and UV-VIS spectroscopic techniques to reveal their structural, morphological and optical details. The blueshift in strong free excitons recombination peak is observed as the morphology of the film changes from spindle shape to nanorods to clustering of nanorods with increase in sol concentration due to quantum confinement effect in the nc-ZnO thin films.
