Abstract

Germanium oxide (GeO2) nanowires have been prepared by heating a mixture of Ge powder and carbon in an Ar + O2 mixture at 900 degrees C. The nanowires have been characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and spectroscopic measurements. The nanowires are single crystalline with diameters in the 15-250-nm range. They exhibit characteristic blue luminescence.

摘要

通过在900摄氏度的氩气和氧气混合气体中加热锗粉与碳的混合物，制备出了二氧化锗（GeO2）纳米线。这些纳米线通过X射线衍射、扫描电子显微镜、透射电子显微镜和光谱测量进行了表征。纳米线为单晶，直径在15至250纳米范围内。它们呈现出特征性的蓝色发光。
