Abstract

From detailed optically detected magnetic resonance measurements in polythiophene, we show that the g=2.003 signal is luminescence enhancing, and that the signal comes from a broad photoluminescence band peaking near 1.65 eV. This band is tentatively assigned to Phe radiative recombination of polarons, with lifetimes between 10-8 and 5×10-5sec.
