Abstract
Photoluminescent and triboluminescent (TrL) properties of PZT materials at room temperature were investigated for the first time in this study. Two emissions centered at 2.0eV and 3.0eV were observed, respectively, which were explained by the self-trapped behavior of the intrinsic defects. Moreover, the strong TrL was observed in the PZT film, which was associated with the oxygen vacancies since the TrL intensity of the PZT film was greatly increased after heat-treatment in a reducing atmosphere. These results make it possible for the PZT material to act as light-emission devices and optical stress sensors.
