Abstract

The electronic relaxation processes in poly(p-phenylene) (PPP) and poly(N-vinylcarbazole) (PVCA) were studied. The fractional thermostimulated luminescence gave evidence of two different thermoactivated processes in PPP and PVCA, taking place in different temperature regions. Fractional thermostimulated luminescence results have been discussed in terms of self-trapping of charge carriers. In PVCA the self-trapping of charge carriers proceeds via formation of dimer cation radicals.
