Abstract

Currently the dye-doping method is widely used in the area of organic light emitting diodes, with its potential of promising the highly improvement of the EL characteristics. The versatile dopants have their optimal doping concentrations of different range. In this paper, we've studied the doping concentration of co-doped emissive layer. With applying graded doping profile, optimal co-doping concentration was clearly derived. The host was Alq 3 and the two dopants were C545T and DMQA respectively.
