ABSTRACT:
A light-emitting device comprises a light-emitting member, which comprises two electrodes, at least two organic electroluminescent (“EL”) materials disposed between the electrodes, a charge blocking material disposed between the electrodes, and at least one photoluminescent (“PL”) material. The light-emitting member emits electromagnetic (“EM”) radiation having a first spectrum in response to a voltage applied across the two electrodes. The PL material absorbs a portion of the EM radiation emitted by the light-emitting member and emits EM radiation having second spectrum different than the first spectrum. Each of the organic EL materials emits EM radiation having a wavelength range selected from the group consisting of blue and red wavelength ranges.
