英文摘要	The magnetic field effects of electroluminescence (MEL) in 4-[dicyanomethylene]-2-t-butyl-6-(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran(DCJTB) doped tri-(8-hydroxyquinoline)-aluminum (Alq(3)) based organic light-emitting diodes were investigated. A linear decrease in MEL with the increase of magnetic field was observed at high magnetic field (> 20 mT) in this doping devices, which has been attributed to the singlet-polaron quenching effect. It was found that the singlet-polaron quenching is magnetic field dependent. Our results showed that singlet-polaron quenching commonly exists in fluorescence OLEDs and induces the linear decrease in MEL. (C) 2014 AIP Publishing LLC.
