Abstract:
Water soluble triethanolamine (TEA) and cysteine capped ZnSe nanoparticles have been synthesized via simple solution based route. The method involves the reduction of selenium followed by the addition of the metal salt and capping group. The pH and metal salts were varied to study their effect on the optical properties and morphology of the particles. The as-synthesised ZnSe nanoparticles properties were studied by UV-Vis, photoluminescence, FTIR spectroscopy, powder X-ray diffraction, transmission electron microscopy (TEM) and high resolution TEM.
