Abstract

The temperature dependence of the current, radiance and efficiency from electroluminescent (EL) devices based on [Ru(bpy) ₃] ²⁺(PF ^- ₆) ₂ was investigated. It was found that the current increased monotonically with temperature from 200-380 K whereas the radiance reached a maximum near T _room. It was analyzed that the quenching of the Photoluninescence (PL) with temperature could be accounted for by the thermal activation to a nonradiative d-d transition. It was also observed that the temperature dependence showed a complex behavior in which transport appeared to be thermally activated with distinct low-temperature and high-temperature characteristics.
