High efficient yellow-green electroluminescence from polymer light-emitting diode on flexible substrate

A highly efficient yellow-green flexible polymer light-emitting diode (PLED) is reported in the study. Poly(ethylene terephthalate) (PET) is used as the flexible substrate. The maximum luminance was 38478 cd/m² The maximum efficiency of PLED was 11.32 cd/A. The electroluminescent peak was at 561.56 nm.
