title: Preparation of ZnO nanocrystals via ultrasonic irradiation.
abstract: A simple and rapid process has been developed for the preparation of nanometer-sized ZnO crystals via ultrasonic irradiation, by which pure ZnO nanocrystals with an average size of 6 nm and narrow size distribution can be synthesized in a short time and without using any solvents for the precipitation of ZnO.
