Fabrication of novel SnO2 nanofibers bundle and their optical properties

Here we report on the synthesis of novel SnO2 nanofibers bundle (NFB) by using ball milled Fe powders via chemical vapor deposition (CVD). The reaction was carried out in a horizontal tube furnace (HTF) at 1100 °C under Ar flow. The as prepared product was characterized by X-ray diffraction (XRD), s...
