Abstract

Organic light emitting diode devices employing organometallic Nd(9-hydroxyphenalen-1-one)₃ complexes as near infrared emissive dopants dispersed within poly(N-vinylcarbazole) (PVK) host matrices have been fabricated by spin-casting layers of the doped polymer onto glass/indium tin oxide (ITO)/3,4-polyethylene-dioxythiophene-polystyrene sulfonate (PEDOT) substrates. Room temperature electroluminescence, centered at ∼1065 nm, was observed from devices top contacted by evaporated aluminum or calcium metal cathodes and was assigned to transitions between the ⁴F_{3 / 2} → ⁴I_{11 / 2} levels of the Nd³⁺ ions. In particular, a near infrared irradiance of 8.5 nW/mm² and an external quantum efficiency of 0.007% was achieved using glass/ITO/PEDOT/PVK:Nd(9-hydroxyphenalen-1-one)₃/Ca/Al devices.
