Efficient and mechanically robust stretchable organic light-emitting devices by a laser-programmable buckling process

Nature Communications, 2016
Highly stretchable organic light-emitting diodes tend to suffer from a lack of mechanical robustness. Here, Yin et al. fabricate ordered buckled films by laying flexible light-emitting diodes on laser-ablated, prestretched substrates. The devices exhibit

Singlet and triplet to doublet energy transfer: improving organic light-emitting diodes with radicals

Nature Communications, 2022
Organic light-emitting diodes must be engineered to circumvent efficiency limits imposed by the ratio of triplet to singlet exciton formation, following electron-hole capture.

Enhanced flexible optoelectronic devices by controlling the wettability of an organic bifacial interlayer

Communications Materials, 2021
A challenge for optoelectronic devices is the differing wettability of the organic active layer and transparent electrodes. Here, an organic interlayer which is hydrophilic or hydrophobic on each side enhances the performance of organic photovoltaic ...

Surface plasmon polariton modification in top-emitting organic light-emitting diodes for enhanced light outcoupling

, 2014
We report on the enhanced light outcoupling efficiency of monochrome top-emitting organic light-emitting diodes (OLEDs). These OLEDs incorporate a hole transport layer (HTL) material with a substantially lower refractive index (∼ 1:5) than the emitter ...
