英文摘要: Based on our recent progresses in organic semiconductor lasers using distributed feedback mechanisms, in particular on the achievements of organic random lasers using "Plasmonic Feedback" in metallic nanostructures, this project intends to develope nano-manufacturing techniques for large-area metallic photonic crystals and to investigate the photophysics of localized surface plasmon resonance and its interaction with molecules, exitons, and charges in organic semiconductors. Then, organic light-emitting and laser devices are constructed using the feedback mechanisms based on the "Plasmon resonance-DFB microcavity" scheme. The optoelectronic properties of particle plasmon resonance is investigated systematically in the photoluminescence and electroluminescence processes. Realization of the optically pumped organic lasers and light-emitting diodes with narrow-band and directional emission using metallic photonic crystals will be the aim of this project. This project introduces for the first time the multifold functions of metallic photonic crystals, which may include the nanostructured electrodes, particle plasmon resonance, and the microcavity feedback mechanisms, into the organic optoelectronic devices. This may lead to a breakthrough in the development of electrically pumped organic lasers.
