Av. Yakimov et al., Selective light induced changes of the EL threshold voltage in poly(phenylene vinylene)-based light emitting diode, SYNTH METAL, 102(1-3), 1999, pp. 1140-1140
We present here a new method for lowering the electroluminescence (EL) thre
shold voltage in polymer-based LEDs. The method consists of spatially resol
ved illumination in the presence of electric field.
