Polymer light emitting devices with Langmuir-Blodgett (LB) films : enhanced performance due to an electron-injecting layer of ionomers.
In: Chemical physics letters, 408
Artikel, Bibliographie
Kurzbeschreibung (Abstract)
Polymer light-emitting devices (PLEDs) have been produced with Langmuir–Blodgett (LB) films from poly(2-methoxy-5-hexyloxy)-p-phenylenevinylene (OC1OC6–PPV) as the emissive layer and an ionomer of a copolymer of styrene and methylmethacrylate (PS/PMMA) as an electron-injection layer. The main features of such devices are the low operating voltages, obtainable firstly due to the good quality of the ultrathin LB films that allows PLEDs to be produced reproducibly and secondly due to the improved electrical and luminance properties brought by the electron-injection layer. Also demonstrated is the superior performance of an all-LB device compared to another one produced with cast films of the same materials.
