제목 Multiscale Architectured Core/Shell Colloidal Particle Assemblies for Optical and Electrochemical Applications
초록 Ensembles of nanoparticles (NPs) have received much attention for their strong potential in a wide array of applications. Here, we introduce some recent works on harnessing multiscale colloidal assemblies for optical and energy storage applications. First, we have established a synchronized synthetic approach of ordered colloidal particles in which the pre-assembly of NPs and subsequent shell coating process are performed simultaneously. This leads to the formation of highly anisotropically extended and structurally stable alignment of nanoparticles with tunable refractive index. In addition, we propose a synthesis of multiscale structured core/shell particles comprising hollow carbon capsules internally encapsulating Si nanoparticle clusters (SNC@Cs). Unlike conventional yolk-shell structured particles, the synthesized SNC@C particles have shown remarkably high initial Coulombic efficiency and extended cyclic stability when used as an anode material for lithium ion batteries.
