Abstract

High-purity BaTiO₃ single crystals (with transition-metal ion impurity levels well below 1016 cm-3 ) and a series of iron-doped BaTiO₃ crystals with iron concentrations ranging from 5 to 1000 ppm were grown. These crystals were annealed in oxidizing and reducing atmospheres and their photorefractive properties characterized. A thermodynamic defect model was used to predict changes in the valence state of the iron as a function of annealing temperature, oxygen partial pressure and iron concentration. It was found that the "pure" crystals were photorefractive and that the saturation diffraction efficiency of gratings established in both the doped and the undoped crystals increased when the crystals were annealed in reducing atmospheres, but did not scale with the concentration of iron in the crystals. The evidence suggests that variable-valent iron ions are not the dominant photorefractive centers in these samples.
