Surface-emitting organic laser based on stimulated resonant Raman scattering

通过在染料掺杂和π共轭薄膜中引入DBR谐振腔和光子晶体，制备了面发射有机激光器件。当这些聚合物薄膜的受激共振拉曼散射与这些谐振器的激光模式耦合时，获得了拉曼激光振荡。为了进一步发展电泵浦有机激光器，利用液晶π共轭聚合物薄膜制备了具有双极性载流子特性的场效应晶体管，并在交流栅下成功地实现了电致发光。

Surface-emitting organic laser devices were fabricated by introducing DBR resonators and photonic crystals into dye-doped and π-conjugated thin films. Raman laser oscillations were obtained when the stimulated resonant Raman scattering from those polymer films was coupled with the lasing modes of those resonators. Towards future development of electrically pumped organic lasers, light-emitting field-effect transistors with ambipolar carrier characteristics were fabricated with liquid crystalline π-conjugated polymer films, and electroluminescence was successfully obtained under AC-gate operations.
