摘要
Multicolor electroluminescence is demonstrated (see Figure) using a photolithographic technique that allows efficient tuning of the emission color of polymer-based light-emitting devices. The devices consist of a single emissive layer of a blend of conjugated polymers, which is exposed to hydrazine during UV irradiation to tune the energy transfer between the host and guest materials. The emission color is dependent on the exposure time of the film.
