Abstract
The organic light emitting diodes (OLED) with a mixed
layer has been prepared. The mixed layer is constructed by mixing
tris-(8-hydroxyquinoline)-aluminum(III) (Alq3) with
[Naphthyl-substituted benzidine derivative] (NPB), and inserted it between
the hole transporting layer of NPB and the emitting layer of Alq3. The
structure of the mixed layer OLED is ITO/
[
,
-tris[3-methylphenyl(phenyl) amino] triphenylamine (MTDATA)(15
nm)/NPB(60-X nm)/NPB:Alq3(Y weight-%)(X nm)/Alq3(60 nm)/LiF/Al.
In this study, the best concentration of Alq3 in NPB is 30 wt% with
the total thickness of 30 nm. The maximum luminescence efficiency is 9.0
cd/A.
