Theoretical and experimental investigations of the intensity- and field-dependent photorefractive response in polymeric composites were presented. Measurements of the decay time constant and the corresponding grating-amplitude were demonstrated in photorefractive composite consists of 1-n-butoxyl-2,5-dimethyl-4-(4'-nitrophenylazo)benzene: poly(N-vinylcarbazole):2,4,7-trinitro-9-fluorenone with a weight ratio 44:55:1. Analysis suggested that two gratings exist simultaneously, one was caused by the photorefractive effect, and the other was caused by the photoisomerization process.
