A new type of flexible transparent electrode is designed, by employing wettability-induced selective electroless-welding of silver nanowire (AgNW) networks, together with a thin conductive iongel as the protective layer. The obtained electrode exhibits high optical transmittance, and excellent air-stability without sacrificing conductivity.

Triplet decay of TADF emitters can be tuned by their molecular structure, leading to the negative temperature dependence of emission decay.

Inverted organic light-emitting diodes (OLEDs) based on thermally activated delayed fluorescence (TADF) emitters achieved a maximum external quantum efficiency of 16.4%.
