Light-emitting electrochemical cells based on an ionic liquid and a polymeric semiconductor were investigated for demonstration of electrically-pumped organic laser. Owing to the electrochemical doping of organic semiconductor by ionic species, we successively prepared a highly-conducting light-emitting layer and achieved very high current density of 1 kA/cm2 by pulse-driving. In addition to the excellent electrical characteristics, amplified spontaneous emission was obtained by optical pumping of the active layer, which indicated the light-emitting electrochemical cells are promising for the platform device for electrically-pumped organic laser.

研究了基于离子液体和聚合物半导体的电化学发光电池，用于电泵浦有机激光器的演示。由于通过离子物种对有机半导体进行电化学掺杂，我们成功地制备了高导电的发光层，并通过脉冲驱动实现了非常高的电流密度为1 kA/cm 2。除了优良的电学特性外，光泵浦活性层还能获得放大的自发辐射，表明该电化学电池有望成为电泵浦有机激光器的平台器件。
