ABSTRACT:
A light-emissive device including first and second electrodes, and a light-emissive layer located between the electrodes and containing organic light-emissive material including a plurality of particles spaced from each other by the light-emissive material, at least some of the particles being capable of injecting positive charge carriers into the light-emissive material and at least some of the particles being capable of injecting negative charge carriers into the light-emissive material; whereby electrical charge may pass between the electrodes via at least some of the particles to cause light to be emitted by the light-emissive material between those particles.
