| 摘 要： | 在多层结构的有机电致发光器件（ＥＬ）研制中，一个最富吸引力的提高器件发光效率的方法是通过选择具有高荧光量子产率的发光染料为掺杂剂，加入到作为主体的电子或空穴传输层内，经电子与空穴在主体化合物层内的复合形成激子，经能量转移，激发染料分子，发射染料荧光．...

| Abstract: | Benzothiazolate
derivative (BT) with high fluorescence quantum yield was synthesized and firstly used as
dopant in blue organic electroluminescent devices. The devices structure ITO/TPD/DPBI2%
BT/DPBI/MgAg was employed, in which TPD is N,N'-bis(3-methylphenyl)-N,N'-diphenyl-1,
1'-biphenyl-4, 4'-diamine and used as a hole transport layer (HTL);DPBI is a dimer of
N-arylbenzimidazoles and functioned as host and electron transporter. In the device with
BT as dopant, blue emission peak around 475 nm and a luminance of 1260 cd/m2
was achieved at a current density of about 400 mA/cm2. The current efficiency
of this device is about 0.50 cd/A at 5 V. |
