摘要

采用湿化学和超声化学两种方法合成了ZnO/姜黄素纳米复合材料。采用x射线衍射（XRD）和透射电镜（TEM）等技术对样品的相纯度和晶粒尺寸进行了表征。利用红外光谱技术研究了姜黄素及其合成的纳米复合材料中存在的有机基团、弯曲、拉伸和振动。利用紫外可见光谱研究了纯氧化锌和氧化锌/姜黄素纳米复合材料的吸收波长。此外，用PL技术研究了分散在水中的姜黄素纳米颗粒的发光特性，发现在紫外激发下，姜黄素纳米颗粒呈现蓝色发光带。在TEM图像中可以清晰地观察到ZnO/姜黄素纳米复合材料的菱形和六边形颗粒。因此，本研究的重点是合成的纳米结构的形状和尺寸依赖的光学性质及其在靶向给药系统纳米医学中的潜在应用范围

Synthesis & Optical properties Of ZnO / curcumin composite nanostructure

ZnO/curcumin nanocomposites have been synthesized by the wet chemical and ultrasound sonochemical approach. Phase purity and crystallite size were examined by using XRD and TEM techniques. The presence of organic groups, bending, stretching, and vibration in curcumin and synthesized nanocomposites was investigated by FTIR techniques. Absorption wavelengths of the pure ZnO and ZnO/curcumin nanocomposites were studied by using UV-visible spectra. Further, the luminescence properties of curcumin nanoparticles that dispersed in water were examined by PL techniques, which show a blue emission band under NUV excitations. Diamond and hexagonal-shaped particles of the synthesized ZnO/curcumin nanocomposites were clearly observed in TEM images. Hence, this work focuses on the shape and size-dependent optical properties of the synthesized nanostructure and their potential scope in nanomedicine for targeted drug delivery system

期刊介绍： The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including: • Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.) • Chemical intermediates • Molecules in excited states • Biological molecules • Polymers. The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example: • Infrared spectroscopy (mid, far, near) • Raman spectroscopy and non-linear Raman methods (CARS, etc.) • Electronic absorption spectroscopy • Optical rotatory dispersion and circular dichroism • Fluorescence and phosphorescence techniques • Electron spectroscopies (PES, XPS), EXAFS, etc. • Microwave spectroscopy • Electron diffraction • NMR and ESR spectroscopies • Mössbauer spectroscopy • X-ray crystallography • Charge Density Analyses • Computational Studies (supplementing experimental methods) We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
