采用简单的物理气相沉积技术，在950-1000 ℃的空气中，氧化钨丝，通过红外辐射加热原位蒸发，在Si基片上制备了WO 3一维纳米结构。大多数纳米结构是具有多边形横截面的纳米棒，宽度为数十纳米。纳米棒为单晶单斜结构，轴向沿[1 0 0]或[0 1 0]方向沿着。此外，还形成了一些六方结构的单晶纳米带，其长度方向沿着[1 1 0]方向。根据它们的晶胞参数讨论了两种不同结构的形成。(C)2002 Elsevier Science B. V.保留所有权利。
A simple physical vapor deposition technique, oxidizing W filaments and in situ evaporating via infrared irradiation heating at 950-1000 degreesC in air, was developed to prepare WO3 one-dimensional nanostructures on Si wafers. Most of the nanostructures were nanorods with polygonal cross-sections, tens of nanometers in width. The nanorods were single-crystalline monoclinic structure, with the axes preferentially aligned along the [1 0 0] or [0 1 0] directions. In addition, some single-crystalline nanobelts of hexagonal structure were formed, with their length directions lying along the [1 1 0] direction. The formation of two different structures is discussed based on their cell parameters. (C) 2002 Elsevier Science B.V. All rights reserved.
