Abstract
Herein, we reported a generalized and fundamental approach to molecular self-assembly synthesis of ZnO hollow spheres by rationally employing spherical reverse micelles. The formation mechanism of shelled structures was proposed in detail. The products were characterized by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The as-prepared ZnO hollow spheres were then used to examine the photodetector performance under ultraviolet (UV) light irradiation, and the device exhibited excellent photoresponsivity and stability. This work should provide a new concept to design and fabrication of other shelled metal oxide hollow structures with enhanced properties for microelectronics, optoelectronics, and other applications.
