Rezumat | |||||||
Currently organic photochromic compounds have been considered as materials of growing importance for use in optical memory applications. They have been characterized by a set of unique characteristics, and could be easily fabricated in different formats and at low-cost. We studied a new class of photochromic composites consisting of carbazole-contained polymeric hosts with spiropyran-substituted dyes. These composites have been synthesized and experimentally characterized as holographic material for direct high-resolution holographic recording in whole visible spectra. We have already concluded some general principles of photochromic media design for achievement of high sensitivity and diffraction efficiency while hologram records. |
