英文摘要： The organic semiconductor lasers (OSL) easily and other optoelectronic devices are integrated together, the blue microcavity laser device in laser display and high capacity optical disc and others have wide application especially. In this program, the organic blue laser devices and characteristics with electrically pumped and multilayer gain medium and one-dimensional photonic crystal microcavity will be studied. In order to improve the luminous efficiency of organic lasers, we will use a multilayer gain medium and a photonic crystal microcavity. Also in order to improve the mobility of electrons and holes and maintaining the electron and hole mobility basic balance, some of the active metal, metal oxide, nanometer graphene, graphene oxides will be doped. The multi-layer laser gain medium of organic laser will use poly fluorene derivatives and related organic materials. The relationship of the microcavity structure, an electron transport layer, molecular structure of organic materials, pumping voltage with the laser quantum efficiency, model and threshold and the width of spectral line of the lasers will be studied. The high efficiency electric pumped photonic-crystal microcavity organic blue laser devices would have been prepared.
