我们提出了一种新颖的光响应绿色和蓝色有机电致发光（EL）器件结合有机EL二极管与钛氧酞菁作为光电导层。通过将红光和近红外（JR）光照射到这些器件，分别产生绿色和蓝色发射，远低于导通电压。结果表明，该器件可作为光开关和上变频器。使用激光脉冲的EL响应时间约为300 μ s。在开启电压以上，观察到EL强度随着光照射的增强，其比率高达10（4）。(C)2003 Elsevier Science B.V.保留所有权利。
We have proposed novel photoresponsive green- and blue-emitting organic electroluminescent (EL) devices combining organic EL diodes with titanyl phthalocyanine as a photoconductive layer. By irradiating red and near-infrared (JR) lights to these devices, green and blue emissions were generated, respectively, well below the turn-on voltage. The results indicate that the devices act as an optical switch and up-converter. The EL response time using a laser pulse was about 300 mus. Above the turn-on voltage, enhancement of the EL intensities was observed with the light irradiation with the ratio of up to 10(4). (C) 2003 Elsevier Science B.V. All rights reserved.
