Catalytic Growth of Semiconducting In2O3 Nanofibers

Abstract

In2O3 nanofibers have been prepared by using a thermal evaporation–oxidation method. The nanofibers generally show rectangular cross sections (see Figure) with different width-to-thickness ratios. The photoluminescence spectrum of these nanowires shows light emission in the blue-green region. By doping with other elements potential applications in opto-electronic nanodevices and nanosized gas sensors could be achieved.
