摘　　要：合成了吩噻嗪(Phenothianzine)聚合物,将其掺入聚乙烯咔唑Poly(N Vinylcarbazole)(PVK)和聚丙烯丁酯(Poly butylacrylate)(PBA)的聚合物(PVK PBA)以及三硝基芴酮2,4,7 trinitro 9 fluorenone(TNF)聚合制成有机薄膜器件.样品在双相干光束作用下,可建立光折射率光栅,其衍射效率可超过30%,并考察了样品折射率光栅形成的动力学过程.我们还实现了全息图象存储,并获得了清晰的存储图象.文章并对相关结果形成的机制做出了定性的分析.In this paper, a organic polymer phenothianzine was synthesized, and polymerized with poly ((N-Vinylcarbazole))(PVK), Poly-butylacrylate(PBA) and 2,4,7-trinitro-9-fluorenone(TNF). When irradiated by two-beams, the sample can set up refractive index grating with the diffraction efficiency over 30%. The dynamic process of the index grating in the sample was observed. The optical holographic storage was achieved and the storage image was very clear. The qualitative explanation to the experimental phenomena was given.
