CdS/CdSe core/sheath nanostructures obtained from CdS nanowires

Abstract

CdS/CdSe core/sheath nanowires with diameters of 7.7/0.75 nm were prepared by treating CdS nanowires with selenium in tributylphosphine (TBP) at 100 °C for 24 h and were characterized by X-ray powder diffraction, transmission electron microscopy, high resolution TEM, UV–VIS absorption spectra, photoluminescence spectra and X-ray photoelectron spectroscopy.
