摘要：
We have developed an electrically-driven flexible polymer microcavity with green- or red-emitting polymer sandwiched between the 3M multilayer flexible polymer distributed Bragg reflector and the aluminum mirror. The nearly all-polymeric flexible planar polymer microcavity of a Fabry-Perot resonator is fabricated by employing transparent conducting polyaniline as an anode and a thin barium layer followed by a thick aluminum layer as a cathode. The all-flexible polymer microcavity is characterized by external quantum efficiency, spectral narrowing, and angle dependence of resonance peaks. Reduced angular dependence of the emission in microcavity with 3M polymer reflector is observed and the reasons for such a reduction are discussed. (c) 2005 American Institute of Physics.
