Synthesis and Characterization ofSemiconductor andSemiconductor-MetalNanoparticlesVon der Fakult at fur Mathematik und Naturwissenschaften der Carl vonOssietzky Universit at Oldenburg zur Erlangung des Grades und Titels einesDoctor rerum naturalium (Dr. rer. nat.)angenommene DissertationvonFrau Elena Selishchevageboren am 4.2.1985 in Woronesch (Russland)Gutachter: Prof. Dr. Joanna Kolny-OlesiakZweitgutachter: Prof. Dr. Jurgen ParisiTag der Disputation: 19.12.2011iiAbstractNanoparticles are promising materials for many physical and chemical ap-plications, because their properties depend on their size and shape, whichcan be controlled during the synthesis.This work is a contribution to the development of colloidal synthesis ofdi erent nanomaterials, such as lead chalcogenide PbE (E = S, Se, Te),indium oxide (In O ) nanoparticles, and hybrid nanostructures, consisting2 3of copper indium sul de selenide (CuInSSe) and gold nanoparticles.After a short general introduction into the theory of synthesis of nanomate-rials, the investigations of the three systems mentioned above are described.In the rst part, nearly monodisperse PbE semiconductor nanoparticles pro-duced via a novel synthesis which includes the occurrence of in situ formed0Pb -particles are shown. Spherical PbSe nanoparticles are further investi-gated with respect to possible application in hybrid solar cells.
