Improved performance of organic light-emitting diodes (OLEDs) as obtained by a mixed layer was investigated. The OLEDs with a mixed layer which were composed of N,N 0 -diphenyl-N,N 0 -bis(1-napthyl-phenyl)-1,1 0 -biphenyl-4,4 0 -diamine (NPB), tris-(8-hydroxyquinolato) aluminum (Alq 3 ) and 4-(dicya
