The development of the organic quantum-well structure devices was introduced systemically.The conventional organic quantum-well structures were fabricated.The optical and electrical properties of the device were measured and the structures were scaled by the small-angle X-ray diffraction pattern.Based on the techniques

the organic quantum-well structure white light-emitting device was first fabricated and the performances were reported on the article.With the analysis of the possible effects on the performances of the organic quantum-well structure which induced by the fabrication technology

in order to decrease the diffusion effect at the interface of the quantum-well layer and barrier potential layer

the organic doping quantum-well structure was bring forward for the first time in the world.The structure consists of the alternating doping and undoping structure

in which the doping layer acts as quantum-well and the undoping layer as barrier potential layer.The performances of the device with the doping quantum-well structure were significantly enhanced and the results were analyzed.The optimum of the number of the quantum-well was also studied

and the result is two.Through suitable selection of the matrix and the dopants

the efficiency of the device would decrease slowly with the increase of the driven voltage.
