| Abstract | A graded doping technique was introduced to fabricate high brightness and high efficiency OLEDs, in which the luminescent layer consists of the mixture of NPB, Alq3 and an emitting dopant 5,6,11,12-petraphenylnaphthacene (Rubrene), where the concentration of NPB raised while the concentration of Alq(3) was declined gradually in the deposition process. This graded doping device exhibited the maximum emission of 49300cd/m(2) at 35V and the maximum efficiency of about 8cd/A at 10V, respectively, which have been improved by two times in comparison with the conventional doped devices. |
