Variations of Fe2+ concentration and light intensity show that two-step excitations via an excited Fe24 state are responsible for the large holographic sensitivity. The experimental results indicate that the dominant charge driving force is the photovoltaic effect. © 1993, Taylor & Francis Group, LLC. All rights reserved. |
