Abstract

A color-tunable electroluminescent device (1) and a method for tuning the color of a white light emitting electroluminescent device is described. The device (1) comprises a first electrode (2) and a second electrode (2) and an electroluminescent layer (5) disposed there between. Said layer (5) comprises a first electroluminescent compound for emitting light of a first color and a second electroluminescent compound for emitting light of a second color, different from said first color. The electroluminescent layer emits light of the first color when the electroluminescent device is electrically biased in one direction and the electroluminescent layer emits light of the second color when electrically biased in another direction opposite the one direction. Said device further comprises means for controlling the relative amounts of power in both directions such that said device emits white light.
