| 内容記述 | We aim to elucidate the chemical damage structure in poly(allyl diglycol carbonate), PADC, exposed to UV photons with a wavelength of 222 nm using FT-IR spectrometric method. The number density of carbonyl (C˭O) in PADC, which composes carbonate ester, is hardly affected by the UV photons below the critical fluence of 3.0 × 1019 photons/cm2. The number density of carbonyl decreases only above the critical fluence, while those of ether and C-O-C in carbonate ester are monotonically cleaved. These findings corroborate the previous result using 28 MeV electron beams, in which the carbonate ester is lost only above the critical fluence of 1.6 × 1015 electrons/cm2, where the overlapping of electron tracks becomes significant. We extend the conventional track overlapping model to clarify the spatial distribution of point-like defects after the UV exposure. The discrete damage is seen at the critical condition, based on the extended track overlapping model. | |||||
