Preparation and Photoluminescence of In2O3 Nanofibers by Electrospinning
Ultra-thin fibers of indium oxide (In2O3) were prepared by sol-gel processing and the electrospinning technique using polyvinylpyrrolidone (PVP) and indium nitrate as precursors. The fibers were characterized by the thermogravimetric analysis, scanning electron microscopy, X-ray diffraction and room temperature photoluminescence spectra. It was observed that the In2O3 nanofibers exhibited photoluminescence peaks centered at 526 and 590 nm, corresponding to the defeat-related deep-level emission.
