We have used a CPM femtosecond laser system with an amplifier pumped by a copper vapor laser to observe the optical resonant Kerr effect in poly (2,5-thienylene vinylene) (PTV) film. The kinetics of the Kerr signal have been theoretically and experim

A composite of poly(p-phenylenevinylene) (PPV) with V2O5 is prepared through sol-gel processing and compared with the corresponding composite with silica. The effective conjugation length as determined by the band gap remains the same when V2O5 is ch
