| 中文摘要 | a highly efficient and colour-stable three-wavelength white organic light-emitting diode with the structure of indium tin oxide (ito)/moo3/n,n'-diphenyl-n,n'-bis (1-naphthylphenyl)-1,1'-biphenyl-4,4'-diamine (npb)/4,4'-n,n'-dicarbazole-biphenyl (cbp): bis(2,4-diphenylquinolyl-n,c-2') iridium( acetylacetonate) (ppq)(2)ir(acac)/npb/p-bis(p-n,n-diphenyl-aminostyryl)benzene (dsa-ph):2-methyl-9,10-di(2-naphthyl) anthracene (madn)/tris (8-hydroxyquinoline) aluminum (alq): 10-(2-benzothiazolyl)-2,3,6,7-tetrahydro-1,1,7,7-tetramethyl-1h,5h,11h-(1)-benzopyropyrano(6,7-8-i,j)quinolizin-11-one (c545t)/alq/lif/al is fabricated and characterized. a current efficiency of 12.3 cda(-1) at an illumination-relevant brightness of 1000 cd m(-2) is obtained, which rolls off slightly to 10.3 cda(-1) at a rather high brightness of 10 000 cd m(-2). we attribute this great reduction in the efficiency roll-off to the wise management of singlet and triplet excitons between emissive layers as well as the superior charge injection and diffusion balance in the device. |
