Abstract :
In the spectra of thermally stimulated luminescence of PVDF the authors observed two relaxation peaks in the low-temperature region: the γ-peak at 120 K and the β-peak at 190 K, the relative value of which correlates to the degree of the sample crystallinity. Molecular movement in amorphous and crystalline regions of PVDF explains their origin, correspondingly. In the region of 320 K in the TL spectra they observed the α-peak. It also shows on the thermally stimulated depolarization curve of PVDF, and is due to electronic processes
