Multilayer light-emitting electrochemical cell device structures
Novel structures and compositions for multilayer light-emitting electrochemical cell devices are described, particularly those that are adapted to work with stable and printable electrode metals, that optimize recombination efficiency, lifetime and turn-on kinetics. In particular, embodiments of the present invention provide improved performance and extended lifetime for doped electronic devices, where ionic doping levels, ionic support materials content, and electronic transport content are advantageously structured within the device. The doping profile of mobile or semi-mobile ionic dopants is intentionally made to be non-uniform to enhance doping in the interface regions of a device where the active layer interfaces with the electrode.
