Infrared Photorefractive Polymer Characterization System
Abstract
A broad array of apparatus for fabricating and characterizing newly-developed photorefractive polymer materials has been purchased with the funds from this DURIP grant. While these pieces of equipment emphasize the infrared range of the spectrum, instruments have also been acquired which measure thermal and dielectric properties of this new and growing class of high-performance materials. A crucially important study of the trapping states in a major class of photorefractive polymers has already been completed, in which the concentration of the fullerene anion has been measured with a near-infrared spectrometer acquired through this grant. The concentration of fullerene anion correlates well with the all-important photorefractive trap density determined by two-beam-coupling experiments, proving that the anion is the primary trapping species. This information will allow careful optimization of future photorefractive polymer materials. At the same time, a full infrared-capable photorefractive polymer characterization system has been constructed, and this apparatus will be applied to understand and optimize photorefractive behavior in a wide array of new materials.
