We will report on the development of nanoparticle films comprising both semiconductor and metal nanocrystals, deployable for printable electronics applications. Such hybrid morphology enables a strong plasmonic effect on optical properties of semiconductor nanocrystals, which could be precisely controlled via film architecture. In particular, plasmon-exciton interactions in the film can be tuned to provide either an enhanced light-emitting or light-harvesting characteristics of semiconductor nanocrystals. Meanwhile, a stable and inert semiconductor matrix should facilitate the compatibility of fabricated films with many device platforms. Alternatively, semiconductor nanocrystal films doped with a small fraction of metal nanoparticles could be utilized in field effect transistors. In this case, metal domains can inject n- or p-type carriers in response to electric field of the gate electrode.
