Abstract
Well aligned washboard belt-like ZnSe nanostructures were prepared by atmospheric pressure thermal evaporation of ZnSe nanoparticles without the use of a catalyst. The phase structures, morphologies, and optical properties of the products were investigated by X-ray diffraction, scanning electron microscopy, high-resolution transmission electron microscopy, and photoluminescence spectroscopy. The temperatures play an important role in controlling the morphologies of samples. A vapor-liquid mechanism was proposed for the formation of ZnSe washboard-like structures. The present synthetic route is expected to be applied to the synthesis of other II-VI groups or other group’s semiconducting materials with controllable morphologies.
