The configuration of the device was ITO/PVK:TPD/BAlq:TBPe:rubrene/Alq"3/Mg:Ag. By adjusting the proportion of the dopants (TBPe and rubrene) in the light-emitting layer, white light with Commission Internationale de l'Eclairage (CIE) coordinates of (0.34,0.39) was obtained at an applied voltage of 8V; the change of emission spectra was minimal when the voltage increased from 5 to 20V. The device exhibited a maximum external quantum efficiency of 0.68% and a brightness of 1020cd/m^2 at 8V, the brightness increasing to 5723cd/m^2 at 17V. |
