论文摘要
我们报告了基于装有纳米结构的KH2PO4（KDP）晶体的宿主矩阵的复合材料的合成和拉曼散射表征。二氧化硅（SIO2）和阳极氧化铝（AAO）用作具有各种孔径，孔间间距和形态的宿主矩阵。通过X射线衍射和扫描电子显微镜研究了纳米复合材料的结构。拉曼散射揭示了SIO2矩阵内部的一维纳米结构KDP的创建。我们清楚地观察到Sio2 + KDP的拉曼光谱中PO4四面体群的拉伸ν1，ν3和弯曲的ν2振动。在AAO + KDP纳米复合材料的拉曼散射光谱中，AAO基质的宽荧光背景在很大程度上占主导地位，从而阻碍了KDP化合物频谱响应的检测。
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.
