摘要:
采用低温热蒸发法在铜箔衬底上制备了大量ZnO纳米带、空心微米球和“海胆”状球.采用XRD、激光拉曼光谱仪、SEM和荧光光谱仪分别对ZnO纳米结构的微结构、形貌和光致发光性质进行研究.分析表明,纳米带的宽度大约为500 nm且长度超过10μm,而空心微米球的直径为5~10μm;ZnO纳米结构的发光主要是较强的蓝绿缺陷态发光,以及弱的紫外带隙态发光.铜衬底上ZnO纳米结构的制备使得ZnO纳米结构和导电衬底之间具有良好黏着性和电接触性.

ZnO Nanobelts and Hollow Microspheres Grown on Cu Foil

Abstract:
ZnO nanobelts, hollow microspheres, and urchins have been prepared on copper foil via a simply low temperature evaporation route. The microstructure, morphologies, and photolu-minescence of the ZnO nanostructures were studied with X-ray diffraction, Raman spectra, scanning electron microscopy and photoluminescence spectra. The width of the nanobelts was about 500 nm and the length was longer than 10μm. The diameter of the hollow microspheres was between 5 and 10μm. A possible growth mechanism of the nanobelts, microspheres and urchins was proposed. The photoluminescence spectrum exhibited strong deep level energy emissions and a weak near band edge emission. These ZnO nanostructures on a copper substrate have the advantages of naturally good adhesion and electrical connection between the ZnO nanostructures and the conductive substrate.
