Abstract：
Modifications in optical absorption of polyethylene terephthalate(PET) films induced by 35MeV/u Ar ion irradiation were studied by means of ultraviolet-visible absorption spectroscopy.A strong increase in absorbance in the ultraviolet and visible regions is observed in the irradiated samples, which is attributed to the formation of a conjugated system of carbon bonds.The effect is found to increase with increase of ion fluence and the mean electronic energy loss in the samples,but to decrease with increase in the optical wavelength.According to the measured optical absorption spectra,modifications of optical energy gap and the mean size of carbon clusters of the PET samples under irradiation are also analyzed and discussed.
