Abstract

The optical and photoconductive fatigue of fast photorefractive polymers have been studied in a family of C₆₀-sensitized polymer composites containing styrene-based chromophores with varying ionization potential. Changes in response time and in photoconductivity were studied for exposures up to 10⁴ J/cm². Increasing the chromophore ionization potential beyond that of the polyvinylcarbazole host was found to stabilize the response time. Studies of the electric-field dependence of the steady-state diffraction efficiency in various samples confirm the role of C⁶⁰ anions as possible traps.
