Efficient white polymer light-emitting electrochemical cells

Abstract

An efficient white polymer light-emitting electrochemical cell has been fabricated with a thin-film sandwich architecture of glass/indium tin oxide/electroluminescent layer/aluminum. The electroluminescent layer uses a blend of a proprietary white light-emitting polymer, ethoxylated trimethylolpropane triacrylate as an ion-transport medium, and lithium trifluoromethanesulphonate as an ionic source. The lithium salt concentration plays a key role in the device performance, and a maximum current efficiency of 8.1 cd A−1 and luminance greater than 10 000 cd m−2 were obtained at 3 wt% salt concentration.
