摘要
Single-layer LEDs were developed using a composite thin film of organometal halide perovskite (Pero) and poly (ethylene oxide) (PEO). Single-layer Pero LEDs have a device structure that resembles “bottom electrode (ITO)/Pero-PEO/top electrode (In/Ga or Au)”. Green emission LEDs with methylammonium lead bromide (bromide-Pero) and PEO composite thin films exhibit a low turn-on voltage of about 2.8-3.1V (defined at 1 cd m−2 luminance), a maximum luminance of 4064 cd m−2 and a moderate maximum current efficiency of about 0.24-0.74 cd A−1. Blue and red emission LEDs have also been fabricated using Cl/Br or Br/I alloyed Pero-PEO composite thin films.
