| Research Abstract |
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.
