Investigation of top-emitting organic light-emitting devices with highly saturated color employing metal-mirror structure
In this work, characteristics of top-emitting organic light-emitting devices (TEOLEDs) having Ag and Au as anode had been investigated. When using the same emitting materials, the performance of TEOLEDs employing Ag as anode was superior to that of the device using Au as anode. Finally, by using the appropriate dopant instead of Alq as emitter, a TEOLED with high power efficiency (8.7lm/w with luminance of 640cd/m2), almost independent on viewing angle had been reported.
