Local structure and near-infrared emission features of neodymium-based amine functionalized organic/inorganic hybrids.

摘要: Nd3+-based organic/inorganic hybrids have potential application in the field of integrated optics. Attractive sol-gel derived di-urea and di-urethane cross-linked poly (oxyethylene) (POE)/siloxane (di-ureasils di-urethanesils, respectively) doped with neodymium triflate (Nd(CF3SO3)(3)) were examined by Fourier transform mid-infrared (FT-IR), Raman (FT-Raman), Si-29 magic-angle spinning (MAS) nuclear magnetic resonance (NMR) photoluminescence spectroscopies, small-angle X-ray scattering (SAXS). The goals this work to determine which cation coordinating site host matrix (ether oxygen atoms or carbonyl atoms) is active each materials analyzed, its influence on nanostructure samples relation properties. main conclusion from study that hydrogen-bonded associations formed throughout play a major role
