Highly efficient and stable hybrid white organic light-emitting diodes(HWOLEDs) with a mixed bipolar interlayer between fluorescent blue and phosphorescent yellow emitting layers are demonstrated.The bipolar interlayer is a mixture of p-type diphenyl(10-phenyl-10H-spiro[acridine-9,9’-fluoren]-3’-yl) phosphine oxide and n-type 2’,2“-(1,3,5-benzinetriyl)-tris(l-phenyl-l-H-benzimidazole).The electroluminance and Commission Internationale de l’Eclairage(CIE1931) coordinates’ characteristics can be modulated easily by adjusting the ratio of the holepredominated material to the electron-predominated material in the interlayer.The hybrid WOLED with a p-type:n-type ratio of 1:3 shows a maximum current efficiency and power efficiency of 61.1 cd/A and 55.8hn/W,respectively,with warm white CIE coordinates of(0.34,0.43).The excellent efficiency and adaptive CLE coordinates are attributed to the mixed interlayer with improved charge carrier balance,optimized exciton distribution,and enhanced harvesting of singlet and triplet excitons.
