Transition-metal chalcogenide nanomaterials show promise for applications in photovoltaics and plasmonic devices. Of these class of materials, Cu2S encompasses the environmentally friendly and earth abundant qualities not afforded to many other heavy metal semiconductors. Copper sulfide nanoparticles are prepared by physical vapor deposition without the surface ligand capping effects known to inhibit and otherwise complicate charge transfer. Another obstacle to the use of copper sulfide for photovoltaics is the self-doping that occurs upon oxidation, which is compensated for here by all-gaseous preparation of Cu2-XS nanoparticles into organic matrices. These films are characterized by X-ray photoelectron spectroscopy, transmission electron microscopy, high-angle annular dark-field scanning transmission electron microscopy, X-ray absorption experiments, and other methods. 2.3± 0.4 nm Cu2-XS nanoparticles with copper in the +1 oxidation state were deposited into pentacene films and additional structural information will be presented.
