Abstract

The photorefractive properties of BaTiO₃ are sensitive to the powder processing and crystal growing techniques. Variations in starting materials, and growth or annealing atmosphere have been shown to significantly impact the concentration and characteristics of photorefractive charge carriers. We have addressed the optimization of the electronic structure of BaTiO₃ by examining process atmosphere and melt additives with the goal to improve the photorefractive sensitivity within the visible and near infrared spectrum.
