ABSTRACT
This paper reports the electroluminescence (EL) characteristics of a single-layer light-emitting diode (LED) with an organic functional layer, which is composed of an organic ionic emissive dye, IR1051, an electron transporting material, 2-(4-biphenylyl)-5-(4-t-butylphenyl)-1,3,4-oxadiazole, and poly(N-vinylcarbazole). The LED exhibits IR EL in the 0.9-1.5 µm range, which is ascribable to IR1051 with reference to steady-state absorption and photoluminescence measurements. The present study demonstrates a class of IR EL materials containing no rare earth ions and compatible with silicon-based photocircuits.
