Abstract A parallel study of switching and the associated luminescence emission has been carried out in pure and Fe-doped BaTiO3 samples in the temperature range-100°C to 130°C that contains the four crystallographic phases of BaTiO3. The main result is the appearance of a second maximum in the switching and light pulses from the Fe-doped samples, that behaves with the applied electric field and temperature in a different way than those single pulses found in pure samples. The integrated light output peaks at the transition temperatures.
