ABSTRACT:
CuInS2nanoparticles have been prepared from single source precursors via microwave irradiation. Also, CuInGaS2alloy nanoparticles have been prepared. Microwave irradiation methods have allowed an increase in the efficiency of preparation of these materials by providing increased uniformity of heating and shorter reaction times. Nanoparticle growth has been controlled in the about 1 to 5 nm size range by variation of thiolated capping ligand concentrations as well as reaction temperatures and times. Investigation of the photophysical properties of the colloidal nanoparticles has been performed using electronic absorption and luminescence emission spectroscopy. Qualitative nanoparticles sizes have been determined from the photoluminescence (PL) data and compared to TEM images.
