TETRA-OLIGOGLYCIDYLCARBAZOLSILANE AS BASE OF PHOTO-SEMICONDUCTING MEDIUM FOR OPTICAL HOLOGRAM RECORDING

摘要

The invention relates to optically active media based on photosensitive polymeric or oligomeric composites with semiconducting properties used for optical hologram construction. The invention is implemented by formation of photo-semiconducting medium for optical hologram recording comprising solid transparent substrate with applied in sequence transparent conductive layer ITO, photosensitive layer based on novel tetra-oligoglycidylcarbazolsilane synthesized by interaction of tetraethoxysilane with oligoglycidylcarbazol and sodium:with high rheological properties, sensibilized with organicdye,.This enables to enhance diffraction efficiency of hologram by 1.7 times and to use lasers with lesser radiant power, thus reducing cost thereof.
