Abstract
Two kinds of quasi-aligned ZnCdO nanostructures, i.e., ZnCdO nanorods and ZnCdO nanoneedles, were synthesized simultaneously by evaporating Zn and Cd powders using Au as a catalyst. The synthesized ZnCdO nanorods have uniform hexagonal crystallographic planes, and their diameters are about 150Â nm. The Cd content of quasi-aligned ZnCdO nanorods was as high as (about) 16.7Â at%. Notably, the ultra-violet (UV) near-band-edge (NBE) emission was red-shifted from 386Â nm (3.21Â eV) to 408Â nm (3.04Â eV) due to the direct modulation of band gap caused by Zn/Cd substitution. Temperature is deemed as a critical experimental parameter for the formation of different morphologies of ZnCdO nanostructures.
