Technological advancements in the synthesis of organic, nanocrystal, and hybrid soft materials has launched a second revolution in the electronics industry, providing the ability to process semiconducting thin films at low temperatures, and to build electronic devices which are lighter, greener, and more flexible. The transition from inorganic bulk to thin-film electronics is expected to have a great impact on green energy technologies like solid-state lighting (SSL) and solar energy harvesting. Our research activities have centered on hybrid integration of organic materials with inorganic components including nano-clustered metal oxides, nanocrystal quantum dots, and nanometer dipole interlayers to realize improved properties and new functionalities. The concepts of strain engineering, bandgap engineering, and delta doping typically used in inorganic semiconductors have been introduced into these new classes of materials, leading to remarkable performance enhancement of light-emitting devices which function as alternative yet greener SSL sources.
