Abstract
The identification of the trapping states with a goal of eventual optimization the trap density. Composites of the general composition poly(N-vinyl carbazole), nonlinear optical chromophore amino-dicyanostyrene, butyl benzyl phthalate and fullerene (PVK:NLO:BBP:C60) sensitizes hole generation for red wavelengths near 650 nm. The spectroscopically determined concentration correlates well with the photorefractive trap density obtained from analysis of the photorefractive performance. The speed of the photorefractive effect is influenced by the possibility that mobile holes can become trapped in the NLO sites during transport.
