Abstract
The dependences of the bulk photovoltaic effect on the composition fraction x, temperature, and on illumination wavelength have been investigated in the (1-x)PbTiO3-xLa(Zn⅔Nb⅓)O3 solid solution ceramics. The composition dependence of the photovoltaic current Jph shows a very similar tendency to that of the remanent polarization Pr, suggesting that Jph is directly related with Pr. On the contrary, the variation of the photocurrent with temperature measured in a sample with x=0.105 reveals an anomalous peak just below the Curie temperature. These characteristics are discussed in comparison with the ceramic BaTiO3 data by Brody.
