摘要：
The optical absorption is studied as a function of gamma-irradiation dose for polyvinylidene difluoride material (PVDF). Optical absorption spectra were measured in the wavelength range from 200 to 1100 nm at different gamma-doses in the range from 25 to 300 Mrad. The absorption coefficient (alpha), absorption index (K) and the values of energy gaps (E(opt)) and (DELTA(E)) are found to be dependent on gamma-doses. The increase in the degree of crystallinity of PVdF samples is due to irradiation.
