Abstract
Eosin dye based poly(methacrylates) with variation in the number of methylene spacers have been prepared by free radical polymerization process. The utility of the polymers for high-density optical data storage using holography has been studied by grating formation with the 514.5 nm line of the Argon ion laser as source. The influence of various parameters on the diffraction efficiency of the polymers has been studied. The effect of increase in the number of methylene spacers, hooked to the eosin blue dye, on the diffraction efficiency of the grating formed has also been discussed. Optical microscopic observations showing grating formation in the polymers have also been presented.
