Abstract
The irradiation effects of intense ultraviolet (UV) light from ArF and KrF excimer lasers on poly(vinylidene fluoride) (PVdF) were studied. The optica l absorption spectroscopy made it clear that irradiation with ArF and KrF e xcimer laser light mainly caused the formation of diene and triene structur es, respectively. From the dependence on the laser intensity it was found t hat ArF and KrF laser-induced reactions proceeded via single-photon and mul ti-photon processes, respectively. The wavelength dependence was explained by photochemical and photothermal effects of ArF and KrF excimer lasers, re spectively. These results indicate that the distinction of the photo-reacti on between the two is closely related to the difference in the absorption s ites.
