Popis:	We report on the observation of time-delayed luminescence of bulk Polyamide-6 polymer material under the room temperature and liquid nitrogen temperature conditions. The excitation was taken from low power diode laser operating at the wavelength 407 nm. The afterglow duration amounts up to several seconds and the decay function was found to coincide with the Becquerel hyperbolic law. The conclusion that we have made with account of the results obtained is the charge-recombination origin of this effect.
