中文摘要： 构建新型的复合纳米材料不仅能为新现象的发现及新机理的研究开辟新的领域，同时也是解决当前国际上传统无机半导体材料光电效率低这一难点的有效途径。基于无机氧化物光电材料在光电领域的重要性，针对ZnO材料较宽的带隙限制其对太阳光中可见区域的光吸收的缺陷，本项目将利用半导体材料间带隙互补的优势，采用无模板电沉积的技术首先构建大面积一维ZnO/CuO纳米结构材料阵列，并进一步通过半导体纳米颗粒与一维半导体纳米结构材料的复合构建出新型的具有较高光吸收效率的复合纳米光电材料，在此基础上进行材料耦合光电现象的探索和研究，以期在低维半导体材料间的耦合机理方面得到发展。本研究不仅可以解决目前单一无机半导体光电材料光吸收效率低的关键性问题，为研究其它无机光电材料的新性能提供了新的思路，而且也为研究纳米材料间新的耦合现象及物理机制提供了重要的研究基础。

英文摘要： The fabrication of new type of composite nanomaterials could not only open up the field for the exploration of new phenomena and the study of new mechanism, but also provide an effective way for the resolvation of the difficulty that the photoelectric efficiency of traditional semiconductor materials is lower at present. In the field of photoelectric material, inorganic oxide material ZnO is a kind of important material with the wider band gap, which will limit the light absorption in the visible region. According to that the compound of the materials with different band gaps could complement the band gaps, we will prepare one-dimensional ZnO/CuO nanostructures arrays with a large area by the electrodeposition without template. Then, we will fabricate the new type of composite nanomaterials with the higher light absorption efficiency using the semiconductor nanoparticles and one-dimension semiconductor nanostructure material. We hope that we could develop the new theory about the coupling mechanism between the semicondutors by exploring its photoelectric properties. The project could not only resolve the lower light absorption efficiency of single inorganic semiconductor photoelectric materials and provide a new train of thought for the new property research of inorganic photoelectric materials, but also provide
