Simultaneous thermoluminescence and thermally stimulated current in polyamide

We have firstly obtained simultaneous thermoluminescence (TL) and thermally current (TSC) spectra in two types of polyamide film, such as, nylons 6 and 11 under study of electron detrapping and recombination. For these are three main relaxation peaks or regions, designated γ, β and α, for convenience, in order of increasing temperature, in the TSC spectra, in contrast, their α relaxation peak in TL spectra disappear. Their center is located at near 180 K, 230 K and 310 K, respectively, at the most, deviates from ±10 K. However, we also observed two anomalous phenomena, first, a very large, short-circuited, thermally stimulated discharge current, up to 10^-8 A, but reversible in for non-polarized nylons 6 and 11, ever after several times repeatedly, second, no TL signals only for nylon 6 film non-poled.
