摘要: The large-scale ZnO rods of submicrometer were prepared on the bare glass using a wet chemical method under different experimental parameters, such as reactant concentration and growth time. microstructure was characterized by X-ray diffractometry (XRD) field emission scanning electron microscopy (FESEM) with energy dispersive spectroscopy (EDX), optical property investigated room-temperature photoluminescence (PL) spectra. XRD FESEM results show that wurtzite structure rod-like is obtained. length (3-8 μm) diameter (400 nm-3 vary parameters. A strong UV at 384 nm weak visible yellow-green around 570 are observed in PL spectrum. After annealing 600 ℃ air, peak intensity increases obviously decreases greatly. near-band-edge attributed to exciton recombination; can be associated defect some complexes may responsible for latter emission.
