Synthesis and Photoluminescence Properties of Zinc Oxide Nanostructures
Two kinds of tetrapod-like zinc oxide nanostructures were fabricated using chemical vapor deposition method under argon and oxygen mixed ambient condition. The source materials were pure zinc powders. No catalyst was used during reaction. X-ray diffraction
scanning electron microscopy
transmission electron microscopy and photoluminescence spectroscopy techniques were used to characterize their structures and optical properties. The nano productions are high purity zinc oxide with the wurtzite structure. Two kinds of zinc oxide nano productions possess three-dimensional structures
which are tetrapod-flake structure and tetrapod-wire structure
respectively. The nano productions have large length-diameter ratio and show a typical nano/micro-structure. By comparing the ultra-violet emission peak and visible emission band of the two zinc oxide nanostructures
the origin of the visible emission and the influence of their structures on optical emission properties are discussed.
