Award Description: The objective of this research is to realize efficient infrared electroluminescence using a hybrid organic-inorganic light-emitting device based on emissive group IV semiconductor nanoparticles including Si, Ge and Si1-xGex. Group IV semiconductor nanoparticles have the potential to be efficient and tunable photon sources in the infrared. To date, these systems have not been extensively studied in light-emitting devices. In this work, performance will be maximized by engineering the device architecture, processing conditions, and nanoparticle passivation length. Device performance will be correlated to nanoparticle film morphology using various microscopies. With an improved understanding of architecture and film morphology for Si-based light-emitting devices, other novel group IV systems will be investigated in order to provide multiple infrared light-emitters. The focus on group IV systems will broaden the study of nanoparticles for photonic device applications, and will also contribute to the basic understanding of radiative and non-radiative processes in these materials.
