| Abstract: | A kind of white OLED with single luminescent layer was designed and prepared,in which rubrene was doped in Liq as single luminent layer.The structure of the devices is ITO/PVK:TPD/Liq:Rubrene/Alq3/Al.The brightness of the devices comes to 3 120 cd/m2(at a driving voltage of 25 V),the CIE coordinates of the typical devices is(0.308,0.347),and the coordinates is very closed to the white equi-energy point.Compared with four types of white organic light-emitting devices,the effects of the luminescent mechanisms... |
