Influence of temperature on the light emission response in electrically polarized graphene oxide films

The influence of temperature on the light emission response in electrically polarized graphene oxide (GO) samples, 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 changes, a blueshift in the emission spectrum was identified, as expected for a semiconductor material. The light emission mechanism was described mainly by thermal emission and temperature dependence was studied. The results suggest that GO films are an attractive material to develop advanced electronics light emitting devices.
