Light‐Absorption Phenomena in Novel Low‐Reflectance Cathodes for Organic Light‐Emitting Devices Utilizing Metal–Organic Mixtures

Low‐optical‐reflectance cathodes (< 2 %, ∼ 45× lower than standard metal cathodes) utilizing a metal–organic mixed layer (MOML) have recently been developed and shown to dramatically enhance display contrast for organic light‐emitting devices. MOML characterization reveals an organic matrix with embedded metal nanoparticles (see Figure), whose surface plasmon resonance is responsible for the layer's light‐absorption properties.
