Paper Abstract

The transient behavior of photorefractive gratings in the polymer composite poly(N-vinyl carbazole) (PVK), 2,4,7-trinitro-9-fluorenone doped with the electro-optic molecules 4- (hexyloxy)nitrobenzene or N,N-diethyl-para-nitroaniline is presented. It is shown that despite the dispersive character of charge transport in polymers, information that allows the estimation of the hole drift mobility is obtained. The change in the hole drift mobility for samples with various trap densities, induced by 4-(diethylamino)benzaldehyde diphenylhydrazone, was measured.
