摘要

The organic semiconductor material having a crystal structure, the feedback structure of one or more, and the light emitting device, it is possible to include a light emitting layer containing a coupling structure. Through which, in the axial plane of the device, it is fed back, whereby the feedback structure of one or more facilitates the stimulated emission of light from the light emitting layer, the light emitted by the luminescent layer It is possible. Coupling structure is attached to the outside of the device part of some of the feedback light. Alternatively, along the axis substantially perpendicular to the plane of the device, the light coupled, may be released at a predetermined angle. The bonding structure and feedback structures are capable continuous variation of the refractive index along the axis corrugated structure, the device plane, and a combination of any of them, or cycle refractive index. The bonding structure and independent of each other, or shared, common parts, the feedback structure is capable of combination with each other.
