Organic light-emitting devices (OLEDs) formed by soft-contact lamination (ScL) show high luminous efficiency (∼ 2.25 cd A–1 with a Au electrode) and better operational stability than similar devices fabricated by thermal evaporation. The laminated electrodes consist of thin films of Au supported by flat or structured elastomeric elements of polydimethylsiloxane. By combining ScL and soft lithography, it is possible to fabricate high-efficiency OLEDs with micrometer-scale light-emitting areas.
