摘      要：Low density ZnO nanorods are grown by modified chemical vapor deposition on silicon substrates using gold as a *** use high resolution photoiuminescence spectroscopy to gain the optical properties of these nanorods in large *** as-grown samples show sharp near-band-gap luminescence with a full width at half maximum of bound exciton peaks at about 300μeV,and the ratio of ultraviolet/yellow luminescence larger than *** spatial and spectral resolved scanning electron microscope-cathodoluminescence is performed to excite the ZnO nanorods in single rods or different positions of single rods with the vapour-solid grovth *** bottom of the nanorod has a 3.31-eV luminescence,which indicates that basal plane stacking faults are related to the defects that are created at the first stage of growth due to the misfit between ZnO and Si.
