Measuring electric field dependent photodegradation and recovery of disperse orange 11 dye doped polymer thin films using photoconductivity and digital imaging microscopy

摘要

One of the limiting factors of optical devices for space applications is photodamage from high intensity lightand radiation. Dye doped polymers offer many advantages in device design but are susceptible to photodamage,especially due to high intensity UV radiation. Several organic dyes have been observed to self heal after photodegradation. We seek to understand the underlying mechanism with the goal of designing materials that aremore robust to photodegradation. We test the hypothesis that photodegradation is due to charge injection intothe polymer and healing due to recombination using photoconductivity and imaging measurements of disperseorange 11(DO11) doped into PMMA.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
