提出了一种双掺杂结构的有机电致发光器件，该器件具有高效率和全光谱白色光发射。器件结构包括铟锡氧化物玻璃衬底/120 A铜酞菁空穴注入层/500 A N，N′-双（1-萘基）-N，N′-二苯基-1，1 ′-联苯-4-4 ′-二胺空穴传输层/110 A 1，4-bis掺杂有0.025% 4-二氰基亚甲基-2-甲基-6- [2-（三氟甲基）苯基]-1，2-二苯乙烯基的（2，2-二苯基乙烯基）联苯（2，3，6，7-四氢-1H，5 H苯并[ij]喹嗪-8-基）乙烯基]-4H-吡喃+三-掺杂有（0.1%）香豆素6的（8-羟基喹啉）（Alq 3）发光层/200 A Alq 3电子传输层/5 A氟化锂（LiF）/铝（Al）。对于100至1000 cd/m2的亮度范围，获得稳定的白色发射[Commission Internationale de l 'Eclairage 1931色度坐标（X=0.30，Y=0.36）]。器件在2.5V下开启。其亮度在9V下为8800 cd/m2，并且最大效率为5lm/W。
A dual doped structure was proposed for obtaining organic light-emitting devices with high-efficiency and full-spectrum white light emission. The device structure included indium tin oxide glass substrate/120 A copper phthalocyanine hole injection layer/500 A N, N′-bis-(1-naphthy)-N, N′diphenyl-1,1′-biphenyl-4-4′-diamine hole transport layer/110 A 1,4-bis(2,2-diphenylvinyl) biphenyl doped with 0.025% 4-Dicyanomethylene-2-methyl-6- [2-(2,3,6,7-tetra-hydro-1H,5Hbenzo[ij]quinolizin-8-yl)vinyl]-4H-pyran+tris- (8-hydroxyquinoline) (Alq3) doped with (0.1%) coumarin 6 emitting layer/200 A Alq3 electron transport layer/5 A lithium fluoride (LiF)/aluminum (Al). A stable white emission [Commission Internationale de l’Eclairage 1931 chromaticity coordinate (X=0.30, Y=0.36)] was obtained for luminance ranging from 100 to 1000 cd/m2. The device turned on at 2.5 V. Its luminance was 8800 cd/m2 at 9 V, and the maximum efficiency was 5 lm/W.
