染料掺杂型有机电致发光器件

Dey-Doping Organic Electroluminescent Devices

叙述了采用共蒸发法进行有机小分子掺杂对有机ＥＬ器件效率、寿命和发光色的影响规律。结果表明，小分子掺杂法不但可以大幅度提高有机ＥＬ寿命，还可以获得希望的发光色，同时还提出了掺杂剂的选择标准。

In this paper, effects of small molecule doping with coevaporation method on effciencies, lifetimes and colors of organic EL devices are reviewed It was indicated that the driving lifetime of organic EL devices not only was increased by the molecule doping, but the required luminescence colors were also acquired In addition the doping materials selecting standards were also suggested
