Notes:
ZnO nanostructures with different morphologies of nanorods, nanoneedles, nanowires,and nanobelts have been synthesized by thermal evaporation of pure ZnO micropowder. Based onthe appearance of the as-synthesized products observed by field emission scanning electronmicroscope (FE-SEM), we show that substrate temperature and catalyst are the critical factors forthe formation of different morphologies of ZnO nanostructures. The photoluminescence (PL)properties of the ZnO nanostructures were investigated. The difference in PL spectra both inintensity and structure for the different ZnO nanostructures are presented. We demonstrate thatunder appropriate synthesis conditions, highly crystallized and defect-free ZnO nano-structures canbe obtained
