Paper Abstract

Recently special attention has been given to the problem of the holographic registration of images and information with the purpose of a solution of various scientific and technical problems. It is well known that carbazol containing polymers, for example, poli-N-carbazolylalcoxymethacrylate (poli-CAM), co-polymers CAM, polyepoxypropilcarbazol (PEPC), have been recommended very well as organic photoconductors, especially in the field of the creation of mediums for information registration, including holograms. The photochemical method of image recording of carbazole-containing polymers films attribute to famous methods of image recording. Our research is aimed at finding of a new photopolymer compositions sensitive in the visible and infrared spectra. We have studied a photopolymer materials, which are doped by amorphous semiconductors. We have used As2S3, S, Se, GeSe as additives of the amorphous semiconductor, and PEPC, PVA, BMA as main polymers. These photopolymer films have been prepared by pouring from solutions. The photopolymer films have been applied both on transparent (polyethylenethereftalat) films and rigid substrates of optical glass. The samples have been obtained with the thickness in the range of 2 μm to 30 μm. The contents of different amorphous semiconductors have beem maintained within the limit of 5 - 40 wt.% of the photopolymer. The variation of the concentration of each component and the transmission spectra have been studied for all the photopolymer films. The experimental measurements of its transmission spectra are evaluated in conjunction with its application for optical holographic recording in visible and infrared ranges. The optical transmission spectra have been measured in optical region from 0.8 μm to 3.0 μm by spectrum-photometer SPECORD 61 NIR and in region from 0.4 μm to 0.8 μm by spectrum-photometer SPECORD UV VIS.
