An OLED device comprises an anode and a cathode, and at least one graded emissive layer disposed between the anode and the cathode, the graded emissive layer comprising first and second materials, wherein a concentration of the first material increases continuously from an anode side of the graded emissive layer to a cathode side of the graded emissive layer, and a concentration of the second material decreases continuously from the anode side of the graded emissive layer to the cathode side of the graded emissive layer. An OLED device comprising a graded emissive layer and a hybrid white OLED device are also described.
