ZnO具有3.37eV的直接带隙和较高的光响应，有望成为日盲紫外探测器的候选材料。在这项工作中，我们提出了使用微波加热生长方法合成的ZnO单晶微管的紫外光电探测性能。ZnO微管具有较快的紫外光响应，截止波长接近370 nm，有望作为高效、低成本的紫外探测器。(C)2007 Elsevier B.V.保留所有权利。
ZnO stands a good chance of being a candidate material for solar-blind UV detection because of its direct band-gap of 3.37eV and high photoresponse. In this work, we present the UV photodetection properties of ZnO single crystal microtubes synthesized using a microwave-heating growth method. The ZnO microtubes exhibited relatively fast UV photoresponse with a cut-off wavelength similar to 370 nm, indicating their potential application as UV detectors with high efficiency and low cost.
