摘　　要：制作了结构为ITO/PVK:TPD/Alq3/Al、分别以PET为衬底的柔性的和以玻璃为衬底的普通的有机电致发光二极管(OLED),对两种器件的电流密度-电压曲线、光电流-电压曲线及量子效率-电流密度曲线进行了测量与分析。结果表明,它们的光电特性非常接近,但柔性OLEDs(FOLEDs)的开启电压略高;在20 V电压驱动下,FOLEDs的亮度达到1 000 cd/m2,量子效率为0.27%。对器件进行了抗弯折性能的测试。Flexible organic light-emitting diodes （FOLEDs） with ITO/PVK ： TPD/Alq3/Al configuration prepared on poly ethylene-tane-phthalate（PET） substrates were fabricated. The curves of the current density-voltage, optical current-voltage and quantum efficiency-current density of the devices were investigated. Compared to those with glass substrates fabricated under the same conditions, the opening voltage of the FOLEDs was a little higher than them,but those characteristics of two kinds of devices were very similar. Under the driving voltage of 20 V,the corresponding brightness and quantum efficiency were 1 000 cd/cm^2 and 0.27%.
