Information Properties of Halogen-Containing Media for Photothermoplastic Recording of Holograms
The effect of halogens in carbazolyl-containing oligomers on the information properties of recording media in the photothermoplastic method of recording holograms is studied. An increase of photosensitivity was observed for such media with halogens present in their composition. It was shown by photoactivated electron paramagnetic resonance that the lifetime of the photogenerated charge pairs is increased in the presence of halogens. This is due to the increased probability of photogeneration of charge pairs in the triplet state for the modified oligomers compared with their analogs. It is presumed that modification of the photoconductive polymers with halogens is one way of increasing their photosensitivity and for other practical applications (photovoltaics, molecular electronics).
