DOIAbstract
[著者版]Transient absorption characteristics of blue-sensitive organic thin films were investigated via a femtosecond pump-probe technique to estimate carrier kinetics. The most important finding is that the long-lived absorbance at 3440 nm increased with increasing the concentration of 1,1-dimethyl-2,5-bis(N,N-dimethylaminophenyl)-3,4- diphenylsilole (NMe2-silole). This fact indicates photoexcited carriers were dislocated in the organic layer, and the doping of NMe2-silole is considered to be useful method to improve photoconductive characteristics of organic devices
