Abstract
The femtosecond third harmonic generaction (THG) output has been measu red from a series of poly(N-vinylcarbazole) (PVK), C-60, mixed and mul tilayer PVK/C-60 films which were ail fabricated by physical jet depos ition technique. There is an enhancement of femtosecond THG output fro m the mixed PVK/C-60 film in comparison with other films. Charge trans fer complex in the mixed PVK/C-60 film was considered to be the main r eason for this increase of che third-order susceptibility.
