Abstract

Multilayer polymer light-emitting diodes (PLED) fabricated by blade coating are presented. Multilayer of polymers can be easily deposited by blade coating on a hot plate. The multilayer structure is confirmed by the total thickness and cross section view in scanning electron microscope. The efficiency of single layer poly(para-phenylene vinylene) copolymer SuperYellow and poly(9,9-dioctylfluorene) (PFO, deep blue) device are 9 cd/A and 1.7 cd/A respectively by blade coating. The efficiency of the PFO device is raised to 2.3 cd/A with a poly[(9,9-dioctylfluorenyl-2,7-diyl)-co- (4,4′-(N-(4-sec- butylphenyl))diphenylamine)] (TFB) electron-blocking layer added by blade coating.
