White‐light‐emitting polymer diodes containing hole‐injection/transport and electron‐injection/transport layers have been fabricated by solution processing. Illumination‐quality light is obtained from these multilayer, high‐performance devices, with stable Commission Internationale d'Eclairage coordinates, stable color temperatures, and stable, high color‐rendering indices, which are all close to those of “pure” white light indicated by the dotted oval in the Figure.
