Growth Mechanism and Optical Properties of Bundle-Like ZnO Nanostructures Synthesized by a Sonochemical Method
Bundle-like ZnO nanostructure was rapidly synthesized by a sonochemical method at 70 °C, using zinc nitrate, citric acid, ammonia, and sodium hydroxide as reactants. The resulting materials were characterized by X-ray diffraction, scanning electron microscopy, and photoluminescence measurements. The bundle-like nanostructure was formed by the anisotropic growth of the ball-like nanostructure. The room-temperature PL spectrum of the bundle-like nanostructure exhibits a weak ultraviolet emission band and a strong visible emission.
