Tuning of electrical and optical properties of organic LEDs using combinatorial device fabrication
Abstract
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.
