Abstract
We report on light scattering measurements in guest/host photorefracti ve polymers doped with different polar dyes as a function of temperatu re and sample composition. Crystallization processes of the polar dye are found to follow a nucleation and growth mechanism. The structure a nd melting point of the polar dye, the storage temperature, and the am ount of plasticizer are shown to exert a major influence on the shelf lifetime of the samples. New composites with high efficiency and long shelf lifetime are presented. (C) 1997 American Institute of Physics.
