Characterizing and fabrication of green polymer light emitting diode using two PFO and F8BT polymers.
2015
In this paper organic light emitting diode production method using combination of two polyflourene (PFO) and F8BT conjugating polymers which emitte green light in wavelength of 540 nm is reported. Considering the fact that emitting spectrum of PFO overlaps with absorption spectrum of F8BT suitably, Forster energy transportes between two polymers is very well. Because of this we used blending of two polymers PFO: F8BT with two weight percentages of 60:40 and 40:60 in light emitting layer. The sample with weight percentage of 60:40 emitted more intense green light and also the current passing through it was 50 mA in 14 voltage which is a suitable current.
