    Abstract: An inorganic nanocomposite is prepared by obtaining a solution of a soluble hydrezine-based metal chalcogenide precursor; dispersing a nanoentity in the precursor solution; applying a solution of the precursor containing the nanoentity onto a substrate to produce a film of the precursor containing the nanoentity; and annealing the film of the precursor containing the nanoentity to produce the metal chalcogenide nanocomposite film comprising at least one metal chalcogenide and at least one molecularly-intermixed nanoentity on the substrate. The process can be used to prepare field-effect transistors and photovoltaic devices.

    Abstract: A high temperature (on the order of about 90° C. or above) non-aqueous synthetic procedure for the preparation of substantially monodisperse IV-VI semiconductor nanoparticles (quantum dots) is provided. The procedure includes first introducing a first precursor selected from the group consisting of a molecular precursor of a Group IV element and a molecular precursor of a Group VI element into a reaction vessel that comprises at least an organic solvent to form a mixture. Next, the mixture is heated to a temperature of about 90° C. or above and thereafter a second precursor which is different from the first precursor and is selected from the group consisting of a molecular precursor of a Group IV element and a molecular precursor of a Group VI element is added into the heated mixture. The reaction mixture is then mixed to initiate nucleation of IV-VI nanocrystals and the temperature of the reaction mixture is controlled to provide substantially monodispersed IV-VI nanoparticles having a diameter of about 20 nm or less.
