Facile Nanowelding Process for Silver Nanowire Electrodes Toward High‐Performance Large‐Area Flexible Organic Light‐Emitting Diodes

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: May 11, 2024

Abstract Despite considerable interest, uniform and robust flexible transparent conducting electrodes (FTCEs) that can be seamlessly integrated used for highly efficient large‐area oganic light‐emitting diodes (OLEDs) remain elusive. In this study, a fabrication of high‐performance OLEDs by exploiting the rapid nanowelding process silver nanowires (AgNWs) onto polyethylene terephthalate substrate under Xe‐lamp irradiation mechanical pressing treatment is reported. The performance AgNWs FTCEs significantly enhanced applying beam 5 s subsequent compression at 20 MPa 15 s, achieving low sheet resistance 26.5 Ω sq −1 , high transmittance 95.2% (at 550 nm), very smooth surfaces with root‐mean‐square 5.4 nm. Meanwhile, nanowelded maintain excellent electrical conductivity (only 2.96% increase in Δ R / 0 ) after 1000 bending cycles. resulting FTCEs‐based green phosphorescent OLED achieves an unprecedented external quantum efficiency (EQE) 23.7% current as 81.5 cd A . Benefiting from properties FTCEs, fabricated large area 25 × mm 2 still retains EQE 22.2% 78.0

Vibration energy harvesting using piezoelectric transduction is becoming a promising alternative to electrochemical batteries for powering the low-powered wireless and portable electronic devices. Unlike typical cantilevered vibration harvesters (PVEHs) where beam with tip mass experienced excitation directly, low-frequency from coupled longitudinal-transverse of two magnetic coupling-based orthogonal beams (LF-PVEH) proposed in this paper. An attractive feature architecture was that auxiliary tolerated high-shock longitudinal meanwhile motion induced transverse oscillation parallel direction via coupling. To verify principle feasibility ascertain effect magnetically on dynamic behaviors power generation characteristics LF-PVEH, theoretical analysis, numerical simulation, experimental testing were conducted, respectively. The results showed when amplitude increased 3 5 mm, output maximum voltage no more. Besides, by increasing proof m1 20 g, corresponding resonance frequency LF-PVEH can be reduced 8.5 Hz, spatial distance Ly 10 optimal effective bandwidth 8 Hz achieved adapt broadband environments. shows reach 0.2 mW at 11 load resistance 540 kΩ.
