| 中文摘要 | the effect of the concentration of 4-(dicyanomethylene)-2-t-butyl-6-(1,1,7, 7-tetramethyljulolidyl-9-enyl)-4h-pyran (dcjtb) as dopant in tris(8-quinolinolato) aluminum (alq(3)) on the charge carrier transport in alq(3):dcjtb was investigated by measuring the steady current-voltage characteristics and the transient electroluminescence. the dopant concentration dependence of the current-voltage relationship clearly indicates the carrier trapping by the dcjtb molecule. the dcjtb concentration significantly affects the electron mobility in alq(3):dcjtb. the mobility has a nontrivial dependence on the doping level. for relatively low doping levels, less than 1%, the electron mobility of alq(3):dcjtb decreases with the doping level. an increasing mobility is then observed if the dopant concentration is further increased, followed by a decrease for doping levels larger than similar to2%. the change of the electron mobility with the dcjtb concentration in alq(3) is attributed to the additional energetic disorder due to potential fluctuations caused by the dipole-dipole interaction of random distribution dopant at the relatively low doping concentration, and to the phase separation at the high doping concentration. |
