Abstract:	摘要： Single-layer and efficient blue phosphorescence organic light-emitting diodes (PHOLEDs) utilizing a small molecule host, bis[3,5-di(9 H -carbazol-9-yl)phenyl]diphenylsilane (SimCP2), as the host material were investigated. All active components including SimCP2, 1,3-bis[(4- tert -butylphenyl)-1,3,4-oxadiazolyl]phenylene (OXD-7), and iridium(III) bis[(4,6-di-fluorophenyl)-pyridinato- N , C $^{2}$] picolinate (FIrpic) were mixed in an organic solution for wet processing in the fabrication of single-layer PHOLEDs. The device's performance significantly exceeds other small-molecule-host, single-layer, blue PHOLEDs fabricated by the solution process. With minimum efficiency roll-off, a maximum current efficiency of 13.6 cd/A, power efficiency of 8 lm/W, external quantum efficiency of 4.71%, and Commission Internationale de L'Eclairage (CIE x,y ) coordinates of $(0.15,0.36)$ at 600 cd/m 2 have been achieved. In addition, the device performance of the solution-processed single-layer PHOLED is much greater than that of its vacuum-deposited counterparts. 出版者： The Japan Society of Applied Physics 出版日期： 2013-01-01 出處： Japanese Journal of Applied Physics, 2013-01, Vol.52 (1), p.012101-012101-6 資源來源： Institute of Physics Journals 識別號： ISSN: 0021-4922 識別號： EISSN: 1347-4065 識別號： DOI: 10.7567/JJAP.52.012101
