INFORMATION PROPERTIES OF HALOGEN-CONTAINING MEDIA FOR PHOTOTERMOPLASTIC RECORDING OF HOLOGRAMS
Abstract
The effect of halogens in the compound of carbazolyl-containing oligomers on the information properties of recording media for the photothermoplastic method of recording holograms is studied. An increase of the photosensitivity of such media with the presence of halogens in their composition has been observed. Using the photoactivated EPR method, it is shown that in the presence of halogens, the lifetime of the photogenerated charge pairs increases. This is associated with an increase in the probability of photogeneration of the charge pairs in the triplet state for the modified oligomers compared to their counterpart. It is assumed that the modification of photoconductive polymers with halogens is one of the ways to increase their photosensitivity, which can be used for other practical applications (photovoltaics, molecular electronics).
