Controlled positioning of metal nanoparticles in an organic light-emitting device for enhanced quantum efficiency

- We demonstrate Au-nanoparticle-embedded OLEDs with enhanced quantum efficiency.
- Au nanoparticles (NPs) are embedded in OLEDs by an aerosol technique.
- The technique is a dry, room-temperature process, compatible with organics.
- It allows for precise positioning of Au NPs while minimizing damage to organics.
