Title: Organic electroluminescent materials and devices

Abstract

An organic light emitting device is disclosed whose emissive layer has a host material, a first emissive dopant, and a second dopant. The second dopant is an excited energy state managing dopant provided in an amount between 2-10 vol. % of the emissive layer and has a lowest triplet state energy level, TM, that is higher than a lowest triplet state energy levels, T1, of both the host and the first dopant and lower than the multiply-excited energy level, T*, of the first dopant.

Light-emitting device with organic electroluminescent material and photoluminescent materials

Patent McNulty, Thomas Francis; Duggal, Anil Raj; Turner, Larry Gene; ...

A light-emitting device comprises a light-emitting member, which comprises two electrodes and an organic electroluminescent material disposed between the electrodes, and at least one organic photoluminescent ("PL") material. The light-emitting member emits light having a first spectrum in response to a voltage applied across the two electrodes. The organic PL material absorbs a portion of the light emitted by the light-emitting member and emits light having second spectrum different than the first spectrum. The light-emitting device can include an inorganic PL material that absorbs another portion of the light emitted from the light-emitting member and emits light having a thirdmore » « less
