ZnO纳米线/纳米棒混合阵列的制备及其光致发光性能研究
Preparation and Photoluminescence Properties of ZnO Nanowire/Nanorod Mix Arrays
摘要
Abstract
Well-aligned ZnO nanowire/nanorod mixed arrays were synthesized on ZnO/Si thin film substrates by a catalyst-free thermal evaporation method.The nanowires and nanorods with diameters of 10-20 nm and 60-160 nm, respectively, were mixed together in the arrays.The ratio between the numbers of nanowires and nanorods was decreasing in the downstream direction on the substrate.Room-temperature photoluminescence measurements showed that the ultraviolet emission intensity of the nanowire arrays was about 5 times higher than that of the nanorod arrays.Continuous illumination with incident laser serves to enhance the ultraviolet emission of the nanowire arrays, and the emission intensity decreased to the original value without the illumination, which could be interpreted by the deserption and adsorption of the oxygen species on the nanowire surface.关键词
