Morphology Control and Cathodoluminescence Properties of ZnO Microflowers Assembled from Nanorods through Hydrothermal Method

20

The authors reported an easy and efficient hydrothermal method to synthesize ZnO microflowers through the self-assembly of nanorods at 150°C.

The experimental results have indicated that the ZnO microflowers have an average diameter of about 2 μm, composed of nanorods with an average diameter of about 200 nm. It is found that the zinc source types, solution pH value, reaction temperature, and reaction time are responsible for the variations of ZnO morphology. Optical properties of the ZnO microflowers have been studied, which show both sharp ultraviolet emission peaks and broad green peaks. The decrease of emission intensity accompanies with decreasing diameter. The ZnO microflowers may have potential applications in photocatalyst or photoelectrochemical cells.
