Singlet and triplet to doublet energy transfer: improving organic light-emitting diodes with radicals
Emrys W. Evans, Alexander J. Gillett, Qinying Gu +5
Organic light-emitting diodes (OLEDs) must be engineered to circumvent the efficiency limit imposed by the 3:1 ratio of triplet to singlet exciton formation following electron-hole…
Doublet-triplet energy transfer dominated photon upconversion
Jianlei Han, Yuqian Jiang, Ablikim Obolda +3
Stable luminescent pi-radicals with doublet emission have aroused a growing interest for functional molecular materials. We have demonstrated a neutral pi-radical dye (4-N-carbazol…
Triplet-Polaron Interaction Induced Upconversion from Triplet to Singlet: a New Way to Obtain Highly Efficient OLEDs
Ablikim Obolda, Qiming Peng, Chuanyou He +5
The triplet harvesting is a main challenge in organic light-emitting devices (OLEDs), due to the radiative decay of triplet is spin-forbidden. Here, we designed and synthesized two…
Organic light-emitting diodes using open-shell molecule as emitter: the emission from doublet
Qiming Peng, Hongwei Ma, Youchun Chen +3
We fabricate OLEDs using a stable neutral π radical, BDPA, as the emitter. There is only one electron in the singly occupied molecular orbital (SOMO) of this open-shell molecule. T…
Driving conditions dependence of magneto-electroluminescence in tri-(8-hydroxyquinoline)-aluminum based organic light emitting diodes
Qiming Peng, Jixiang Sun, Xianjie Li +2
we investigated the magneto-electroluminescence (MEL) in tri-(8-hydroxyquinoline)-aluminum based organic light-emitting diodes (OLEDs) through the steady-state and transient method…
