基于纳米压印 PET 基底的高效柔性有机电致发光器件
High-efficiency flexible organic light-emitting diodes on nanoimprinted PET substrate
摘要
Abstract
Flexible organic light emitting diodes (FOLEDs)have attracted an amount of attentions due to their advantages in power-consumption and color-quality for lighting and display applications.Al-though the indium-tin-oxide (ITO)-coated glass substrates are widely used in OLEDs,their brittle nature limits the further development of flexible OLEDs for some special products.Here,we present a device structure which uses plastic PET as the substrate and spin-coated high-conductivity PEDOT∶PSS as the anode.Based on this OLED device structure,Moth’s eye nanostructure is imprinted on OLED to introduce optical outcoupling structure and increase the light outcoupling efficiency.The green flexible OLEDs on this substrate exhibit superior optical and electrical characteristics,showing a power efficiency of 36.10 lm.W-1 at 1 000 cd.m-2 .By introducing a nanoimprinted light-outcoupling structure on the PET film,flexible OLEDs can yield a power efficiency of 80.46 lm.W-1 at 1 000 cd.m-2 with excellent optical and electrical characteristics.In the bending tests,the FOLEDs show great mechanical stability in luminance after bending 200 cycles in 180°.It is demonstrated that the PET-PEDOT∶PSS sub-strate of the flexible OLED can work as an alternative for the counterpart on ITO-glass substrate for the use in wearable and mobile communication devices.关键词
