摘要：
The range of possibilities in controlling the color of an organic semiconductor based light emitter diode (LED) by incorporating the active layers in a multimode Fabry-Perot cavity is demonstrated. The combination of carefully designed multimode microcavities and electroluminescent organic semiconductors makes possible the realization of mixed colors such as white, purple, etc, with a single LED. The parameters affecting the color include the total optical thickness of the device and the position of the electromagnetic-field antinodes with respect to the location of the emitting dipoles. The electrical characteristics and quantum efficiency of such devices are also reported. (C) 1994 American Institute of Physics.
