Holographic recording characteristics of the unmodified and modified by sodium citrate Fe3O4nanoparticles dispersed in conventional organic photopolymers were studied. The hybrid photopolymer exist the mutual diffusion process and antiwrinkle effect in the experimental system was verified. The results of the experiment show that the incorporation of the both two kinds of Fe3O4nanoparticle leads to an improvement of the holographic performance, but the incorporation of the modified Fe3O4nanoparticle shows a higher holographic performance. The maximum diffraction efficiency reach to 90%, the maximum refractive index modulation arrives at 2.14×103, and the volume shrinkage reduces to 0.8%. All of the results demonstrate that the incorporation of modified Fe3O4nanoparticle is more conductive to improving photopolymer holographic performance.
