Abstract :
We have obtained simultaneous thermoluminescence (TL) and thermally current (TSC) spectra in two types of polyamide film, nylons 6 and 11, to study electron detrapping and recombination. There are three main relaxation peaks or regions, designated γ, β and α in order of increasing temperature, in the TSC spectra. In contrast, the α relaxation peak in TL spectra disappears. The centers of the peaks are located near 180 K, 230 K and 310 K, respectively. However, we also observed two anomalous phenomena: a very large, short-circuited, thermally stimulated discharge current up to 10-8 A, but reversible for non-polarized nylons 6 and 11; and no TL signals for non-poled nylon 6 films
