纳米ZnO的研究及其进展

纳米ZnO的许多优异性能使其成为人们研究的热点并得到广泛的应用。随着ZnO颗粒尺度的不断减小，其量子限域效应越来越明显，观察到电荷载流子，声子，光子的局域化效应；表面、界面态对其性质影响逐渐明显，通过表面修饰和置入多孔及束管等束缚结构，可有效增强ZnO紫外（一个量级）或可见光区（1－2个量级）的发射强度；并使ZnO的电导率，磁化率有很大提高，纳米ZnO与其他材料的复合体系能得到一些新的功能材料。纳米ZnO的自组织行为，使人们可以获得许多形态各异，特殊用途的纳米材料及器件。本文综述了近年来纳米ZnO的研究新动态。

Studies and Development of Nano-ZnO

With many special properties, nanostructure ZnO has become a focused research work recently and being applied widely. Many new interesting phenomena of quantum spacial confinement effects such as Anderson Localization of carriers, photons, phonons, have been discovered and the photoelectric properties of nanosize ZnO change obviously after treatment under different conditions, especially capped with other molecules or in well-confined media materials. Self-organized growth of ZnO brings up a lot of exciting structures and novel properties and provides some good ideas for designation and application of ZnO as semiconductor materials and devices. In this paper, the studies and development of nanostructure ZnO in current years were summarized.
