采用溅射法制备金属Cu薄层，热氧化法制备CuO纳米线。研究了氧化温度和氧化气氛对氧化过程的影响，找到了最佳生长参数。氧化参数和形貌之间有很强的关系。利用纳米线的垫基器件，初步评价了该传感材料对各种氧化还原目标气体的响应，从而证实了CuO NWs作为潜在传感材料在一定条件下的功能特性，并证实了该材料的p型电导响应。(C) 2013 Elsevier B.V.版权所有
CuO nanowires (NWs) were grown by thermal oxidation of metallic Cu thin layer deposited by sputtering on different substrates. Optimal growth parameters were found, studying the influence of the oxidizing temperature and the atmosphere during the oxidation process. A strong relation between oxidation parameters and morphology has been detected. The preliminary response of this sensing material, using nanowire's mat-based device, to various oxidizing and reducing target gases has been evaluated, in order to corroborate the functional properties of the CuO NWs as potential sensing material under certain conditions and to confirm the p-type conductometric response of the material.
