Tuning of Electrical and Optical Properties of Organic LEDs Using Combinatorial Device Fabrication

摘要

The capabilities of combinatorial methods are presented in order to get a detailed understanding of the electrical and optical properties of organic light-emitting devices (OLEDs), to optimize their performance and to provide reliable data for device modeling. We show results on multilayer OLEDs ranging from the conventional copper-phthalocyanine (CuPc)/ N,N′-di-(naphtalene-1-yl) -N,N′-diphenyl-benzidine (NPB) and tris-(8-hydroxy-quinolinato)aluminum (Alq) tri-layer device to double-doped, deep-red emitting OLEDs.
