摘要

采用化学气相沉积方法

在氩气和氧气混合气氛下制备了两种四角结构的纳米氧化锌。初始反应物为纯锌粉

反应过程中没有采用任何触媒。采用X射线衍射、扫描电子显微镜、透射电子显微镜、光致发光光谱研究了纳米产物的结构和光学性质。获得的纳米产物为高纯的纤锌矿结构氧化锌。两种氧化锌纳米产物具有三维立体的四角结构

分别为四角锥-片状结构和四角锥-线状结构

具有较大的长径比

呈典型的微/纳结构。通过对两种氧化锌纳米结构的紫外发射峰和可见发射带的对比研究

探讨了氧化锌纳米产物可见发射带的起源

以及影响其发光性质的主要因素。

Abstract

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.
