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.
Many excellent properties of nano-ZnO make it a hot research area and have been widely used.With the continuous reduction of ZnO particle size, the quantum confinement effect becomes more and more obvious, the charge carriers, phonons, photons The effects of surface and interface states on the properties are obvious. Surface modification and implantation of porous and bundled structures can effectively enhance the UV (one order of magnitude) or visible (1-2) Level) emission intensity; and ZnO conductivity, magnetic susceptibility has greatly improved nano-ZnO and other materials composite system can be some new functional materials. Nano-ZnO self-organization behavior, so that people can get many forms Different, special purpose nanomaterials and devices.This paper reviews the recent developments of nano-ZnO research.
