摘要
The femtosecond third harmonic generaction(THG)output has been measured from a series of poly(N-vinylcarbazole)(PVK),C_(60),mixed and multilayer PVK/C_(60) films which were all fabricated by physical jet deposition technique.There is an enhancement of femtosecond THG output from the mixed PVK/C_(60) film in comparison with other films.Charge transfer complex in the mixed PVK/C_(60) film was considered to be the main reason for this increase of the third-order susceptibility.
