Abstract
ZnO nanocrystals with hexagonal structure (zincite) were prepared by
simple chemical method. In order to optimize the properties of ZnO
nanocrystals we grow those using different solvents (distilled water,
ethanol, methanol and acetone). The effects of solvent on the
nanostructure and optical properties of ZnO were investigated by X-ray
diffraction (XRD), high resolution transmission electron microscope
(HRTEM), and UV – VIS spectrophotometry. The effect of solvent on
the yield, lattice parameters, particle size, microstrain, shape and energy
gap of obtained ZnO nanocrystals were studied.
