Abstract

We present the realisation of efficient polymer light emitting diodes (PLEDs) with yellow emission in a single-layer configuration. We found that the external electroluminescence-quantum efficiencies of PLEDs made of a blend of a blue emitting laddertype poly(p-phenylene) (m-LPPP) and small amounts of an orange emitting poly(decyl-thiophene) (PDT) are significantly improved to 4.2% compared with PLEDs fabricated of pure m-LPPP (2%). In this paper, electroluminescence and photoluminescence properties of different PLEDs consisting of m-LPPP and different amounts of PDT are compared. The results are discussed in terms of excitation energy transfer of Förster type and charge transfer.
