| 摘 要： | 利用热蒸发方法,在硅衬底上制备出立方MgZnO纳米线。以Mg粉为源材料,所制备的为立方相MgO纳米线。以Mg粉和Zn粉混合物为源材料,可以制备出立方相MgZnO纳米线,Zn含量7%,直径200～300nm,具有单晶结构;同时产物中还包括六方相ZnO纳米线,直径30nm左右。MgZnO纳米线中Zn含量远低于源材料中的Zn含量,这可能是ZnO和Zn的蒸汽压远大于MgO和Mg的缘故。

| Abstract: | Cubic MgZnO nanowires were prepared on silicon substrates by a thermal evaporation method.MgO nanowires could be prepared using Mg powders as the source material.MgZnO nanowires could be obtained using the mixture of Mg and Zn powders as the source materials,with the Zn content of 7at% and the diameter of 200-300nm,and there were hexagonal ZnO nanowires coexisting with the cubic MgZnO nanowires in the product.Both the MgZnO and the ZnO nanowires were single crystals.The Zn content in MgZnO nanowires was much lower than that in the source material,which may be due to the higher vapor pressure of ZnO and Zn than MgO and Mg. |
