摘　　要：光折变聚合物是一种新型的光折变材料,化学复合纳米CdS粒子作为光敏剂在激光辐照下产生载流子,克服了物理掺杂易产生相分离等不利因素。以PVK基体上化学复合CdS纳米粒子为基础,制备了有机-无机纳米光折变聚合物材料。对PVK-CdS薄膜进行了激光辐照下的光电导性能研究并对光折变样品膜进行了二波耦合实验,获得了较大的耦合增益系数。Photorefractive polymer is a new kind of photorefractive material . As a photosensitizer , CdS was prepared by chemical means. In this paper, a novel organic-inorganic nanoparticles hybrid photorefractive material was prepared. It was researched on the photoconductivity of PVK-CdS film under illumination at excitation wavelengths of 632.8 nm. Favorable gain coefficient was achieved in two-beam coupling measurement.
