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

Highly efficient and air-stable Eu(II)-containing azacryptates ready for organic light-emitting diodes

Nature Communications, 2020
Though divalent-europium-based complexes are promising materials for next-generation light-emitting devices, their poor air stability limits their applicability.

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 ...
