Abstract

Through hydrothermal process, different morphology ZnO particles are prepared with zinc acetate dehydrate and ammonia used as main resources. The microstructure, morphology and photoluminescence properties of the as-prepared products are characterized by x-ray diffractometer, scanning electron microscope and photoluminescence spectrum, respectively. The results indicate that the as-prepared products are ZnO single crystalline with hexagonal wurtzite structure. The morphology change from rod-like to flower-like and PL intensity enhances when the growth temperature is increased from 120°C to 200°C. CTAB greatly improves the crystalline of ZnO crystals.
