双染料敏化的光致聚合物全息特性研究

The holographic storage characteristic of a new kind of photopolymer co-sensitized by two dyes is studied.The photopolymer is composed of acrylamide and methylenebisacrylamide as monomers, polyvinylalcohol as the polymeric matrix, Eosin Y and Methylene as mixture photoinitiators. Diffraction efficie
