Thermal chemiluminescence from γ-irradiated polytetrafluoroethylene and its emission mechanism: Investigation by multichannel Fourier-transform luminescence spectroscopy

- Chemiluminescence of γ-irradiated polytetrafluoroethylene was measured.
- Emission appeared both in air and in N2 but disappeared within a few minutes.
- Time evolution of spectra evidenced the existence of one kind of luminophore.
- From the temperature dependence, an emission mechanism was proposed.
- The mechanism was used to understand chemiluminescence of polypropylene.
