Study of the light emission response in electrically polarized graphene oxide films at different temperatures

The study of the light emission response in electrically polarized graphene oxide (GO) samples at different temperatures is presented here. GO films were synthesized by employing the double thermal decomposition (DTD) method. Compositional, vibrational, morphological, and electrical properties were studied. Results revealed that as the temperature (T) changes, a slight shift in the emission spectrum was identified, as expected for a semiconductor material. The light emission mechanism was described mainly by thermal emission at all temperatures. These results suggest that GO films are an attractive material to develop advanced electronics light emitting devices.
