摘要
芯 -壳结构复合纳米颗料因其独特结构而具有许多奇异的性质 ,尤其体现在可人工设计和可控的光学性质上 :根据不同的性质要求 ,通过改变组分和壳层与芯部的相对尺寸来实现光学性质在很宽波段范围内的可调特性 .这一特性在光敏器件 (如光开关、光过滤器 )以及下一代的纳米光子学等很多领域有着广阔的应用前景 ,并在目前红外材料的改性上也会大显身手 .文章介绍了几种芯 -壳复合纳米颗粒的合成及其性质研究现状 ,并作相应的展望 .
Due to their unique structure, core-shell structure composite nanoparticles have many unusual properties especially controllable optical properties, which can be regulated in a broad spectral coverage through changing the structure, components or ratio of core and shell size. These optical properties can be extensively used in optical switches, optical filtration, next generation nano-photonics and improving the properties of infrared materials. This paper reviews current research on the synthesis properties of various types of core-shell nanoparticles.Future prospects are also presented.
