Change in Electroluminescence Activity in Polymers Prior to AC Dielectric Breakdown

Abstract

The electroluminescence activity of different polymers (LDPE, PI, PET, PP and PEN) has been investigated from low to high AC 50 Hz electric fields. Experiments have been focused on the evolution of the electroluminescence intensity versus applied voltage. Three different electroluminescence regimes have been distinguished for both studied polymers.
