We report on the synthesis and Raman scattering characterization of composite materials based on the hostnanoporous matrices filled with nanostructured KH2PO4 (KDP) crystal. Silica (SiO2) and anodized aluminium oxide (AAO) were used as host matrices with various pore diameters, inter-pore spacing and morphology. The structure of the nanocomposites was investigated by X-ray diffraction and scanning electron microscopy. Raman scattering reveals the creation of one-dimensional nanostructured KDP inside the SiO2 matrix. We clearly observed the stretching ν1, ν3, and bending ν2 vibrations of PO4 tetrahedral groups in the Raman spectrum of SiO2 + KDP. In Raman scattering spectra of AAO + KDP nanocomposite, the broad fluorescence background of AAO matrix dominates to a great extent, hindering thus the detecting of the KDP compound spectral response.
