Abstract
The pulse radiolysis of low density polyethylene (LPDE), using optical absorption detection and emission spectroscopy, has been investigated in the temperature range 6–150 K, the experiments being complemented by a study of the photoluminescence.
It was found that excitons can be autolocalized at temperatures below 20 K, and this process is strongly dependent on the thermal history of the sample.
