Zinc oxide hexagram microrods

摘要：

Zinc oxide (ZnO) microrods were grown by the floating zone method, the as-grown ZnO microrods have uniform size. Scanning electron microscope image reveals that the ZnO microrods are grown with a hexagonal structure, well faceted ends and side surfaces. Most of ZnO microrods have diameters of about 20-30μn and lengths of about 1-2 mm. Polazizing microscopy image of ZnO microrods shows that they have high crystal quality. The X-Ray diffraction pattern shows that microrods have vertical orientation. The Raman spectra demonstrate that the vibrational mode of wurtzite-type ZnO clearly. The room temperature photoluminescence measurements indicate that the microrods have a relative strong ultraviolet (UV) emission and very weak green emission.
