报道了一种新型、双染料共同敏化的光致聚合物材料,该材料以丙稀酰胺和双丙稀酰胺作为单体,聚乙烯醇为聚合物基质,两种染料曙红Y和亚甲基蓝作为光引发剂。实验结果表明,该材料在四种波长的激光照射下,其最大衍射效率均不低于25%,最大可达54.8豫。通过采用多波长存储技术,分别利用四种不同波长的光在该聚合物膜上同一位置存储了四幅不同的图像,取得一定的效果。
A novel, dual dye sensitized photopolymer material was reported that uses acrylamide and bisacrylamide as monomers and polyvinyl alcohol as the polymer matrix, with two dyes, Eosin Y and Methylene Blue, as the Photoinitiator. The experimental results show that the maximum diffraction efficiency of the material under the four wavelength laser irradiation is not less than 25%, the maximum up to 54.8 Yu. By using multi-wavelength storage technology, four different images are stored at the same position on the polymer film using four different wavelengths of light, respectively, and achieved certain effects.
