说明

氧化锌是一种具有多种技术应用的宽带隙半导体。已知表现出n型导电性。它具有半导体和压电双重特性。其结构具有多个由四面体配位的 O2- 和 Zn2+ 离子组成的交替平面，沿 c 轴交替堆叠。 ZnO 中的这种四面体配位是其非中心对称结构的原因，因此具有压电和热电特性。已经通过固-气相热升华技术合成了纳米梳、纳米环、纳米螺旋/纳米弹簧、纳米带、纳米线和 ZnO 纳米笼。
氧化锌纳米颗粒可以作为抑制抗癌细胞的潜在药物，也可以在药物输送中找到应用。它们还可以像太阳能电池中的金属氧化物半导体纳米材料一样发挥作用。

氧化锌可用作催化剂来研究甲醇合成的机理。它有各种半导体器件和荧光粉

一般描述

Zinc oxide is a wide-band-gap semiconductor having various technological applications. It is known to exhibit n-type conductivity. It has semiconducting and piezoelectric dual properties. Its structure has number of alternating planes composed of tetrahedrally coordinated O2- and Zn2+ ions, stacked alternately along the c-axis. This tetrahedral coordination in ZnO is responsible for its noncentral symmetric structure and consequently imparts piezoelectric and pyroelectric properties. Nanocombs, nanorings, nanohelixes/nanosprings, nanobelts, nanowires and nanocages of ZnO have been synthesized by a solid-vapor phase thermal sublimation technique.
Zinc oxide nanoparticles can serve as potential agents to suppress anti-cancer cells and also find applications in drug delivery. They can also act like metal oxide semiconductor nanomaterials in solar cells.
 

应用

Zinc oxide may be employed as catalyst to investigate the mechanism of methanol synthesis. It has various semiconductor device and phosphor applications.4
用于制备NaZnSiO3OH，一种新型手性骨架材料，其在离子交换、吸附或催化方面具有潜在的应用价值。
