Studies on the Synthesis, Characterization and Applications of Core shell Nanoparticles with an Ultrathin Shell

Abstract

核壳结构纳米粒子是复合纳米粒子的一种形式,构成核壳结构纳米粒子的不同材料之间以互相包裹的关系存在。相比于单纯纳米粒子,核壳结构纳米粒子具有优越的性能,在物理、化学、生物学等领域有着广泛的应用。超薄壳层核壳结构纳米粒子具有几个原子层或者几个nm的壳层厚度,是核壳结构纳米粒子的一种特殊形式。由于壳层的超薄性显示出的特殊效应,如隔绝效应、拉曼增强效应、几何效应、电子效应等,超薄壳层核壳结构纳米粒子在壳层隔绝纳米粒子增强拉曼光谱(SHINERS)技术中起着核心作用,在电催化、生物分析中也有着重要的应用。 本论文着眼于各类超薄壳层核壳结构纳米粒子的合成、表征和应用。具体地,我们开展了如下三方面的工作...Core shell nanoparticles are a kind of composite nanoparticles, in which one component material is coated on another. Better than pure nanoparticles, core shell nanoparticles show some advanced properties and have wide applications in physics, chemistry, biology and so on. Ultrathin-shell core shell nanoparticles is a specific form of core shell nanoparticles and have a shell thickness of only a f...学位:理学博士院系专业:化学化工学院_物理化学(含化学物理)学号:2052008015018
