摘要
报道了一种对绿光敏感的以丙烯酰胺为单体的光致聚合物,该光聚物由单体、光引发剂、共引发剂和成膜物组成。可以得到材料的最大衍射效率为55%。将光聚物用不同温度进行烘烤加热,可以看到材料的折射率调制度会增加。使用角度复用技术在光聚物中存储10幅全息图,说明所研究材料有希望应用于大容量体全息存储。
Green light sensitive acrylamide-based photopolymer system was prepa red. The photo-sensitive medium is composed of monomer, photoinitiator, coinitiator and polym eric film-formingbinder. Diffraction efficiency of the photopolymer as high as 55%could be obt ained. The photo-polymer were baked under different temperature. It is found that the refractiv e modulation increasesas the baking temperature increases. Ten holograms can be stored in this mediu m using angle multi-plexing technology. It is promising of our material for high-density volume d ata storage.
