Preparation of SiOxNanowires by Hydrothermal Method and Their Photoluminescence
-
Abstract
SiOx nanowires were successfully fabricated by a hydrothermal method using SiO powder as raw material.SEM and TEM photos show that the diameter and the length of these nanowires are about 100~200nm and tens of microns,respectively.EDS was introduced to quantitatively analyze the components and show that SiOx nanowires are only composed of Si and O.The PL spectrum shows that the nanowires have two fluorescent excitations at 426 and 446nm.The best preparation condition has been obtained by a series of contrastive experiments with different conditions.Meanwhile,a mechanism is given in this letter for the synthesis of SiOx nanowires by the hydrothermal method.-
