In this paper, we present the formation of high quality trigonal phase selenium (t-Se) scrolled nanotubes and nanowires at 100 degrees C by a simple wet chemical method using of Na2S as new reducing agent and poly(vinylpyrolidone) (PVP) as the stabilizing agent. The Na2S used in this method is not only cheaper and easily available but also easy to handle as compared to many earlier reported inorganic reducing agents e.g., hydrazine hydrate, hydroxyl amine hydrochloride, sodium borohydride, H2O2 etc. The phase purity of the as obtained product is confirmed by X-ray diffraction (XRD), Raman spectroscopy. We have also proposed a possible growth mechanism for the formation of scroll-type nanotubes on the basis of a series of scanning electron microscopy (SEM) and transmission electron microscopy (TEM) studies of the product obtained at different reaction durations. |
