Green polymer light-emitting device preprared for next-generation flexible electronic application

Abstract

An efficient flexible polymer light-emitting device (PLED) was fabricated for next-generation flexible electronic application. The substrate was flexible polyethylene terephthalate (PET). The polymer, poly(2,3-dibutoxy-1,4-poly(phenylene vinylene)) (DBPPV), was light-emitting material. From the J-V characteristic, the threshold voltage was determined to be 4.7V for flexible PLED. The maximum luminescence was 10235 cd/m2. The maximum efficiency of green flexible PLED was 3.49 cd/A.
