Organic-inorganic nanocomposites consisted of photocurable acrylate monomers and inorganic nanoparticles (NP) suitable for the fabrication of diffractive optical elements (DOE) by holographic exposure have been developed. Via capping of the NP surface with proper organic ligands the problem of NP aggregation in organic matrix was avoided. Using the NP of different nature and properties (metal oxides, phosphates, semiconductors and noble metals), the photopolymer materials for efficient holographic DOE as well as for specific optical and photonic elements can be designed. Dependence of diffractive and optical properties of the gratings on the material formulation and on exposure conditions are shown.
