Paper Abstract

The optical nonlinearity of the combination of films of poly(N-vinylcarbazole), abbreviated as PVK, and fullerene C60 has been investigated by third harmonic generation (THG) measurement by using 1064 nm picoseconds (ps) and 790 nm femtosecond (fs) laser beams, respectively. More intense signals were observed from the mixed and multilayer PVK/C60 films than those from pure C60 and PVK films. This signal enhancement was attributed to the complex and carriers produced by the photoinduced charge transfer (CT) process between PVK and C60 molecules in the combination films.
