Nanoparticle-induced refractive index modulation of organic-inorganic hybrid photopolymer.

An organic-inorganic photopolymers have been studied for their potential in of reducing the volume shrinkage during photopolymerization and enhancing the dimensional stability of photopolymers. We demonstrate the diffraction efficiency of photopolymers could be significantly enhanced by the interfacial interactions induced at the surface of inorganic nanoparticles.
