报告内容:

A promising approach of designing mesostructured materials with novel physical behavior is based on combining unique optical and electronic properties of solid nanoparticles with long-range ordering and facile switching of soft matter. This lecture will describe how we practically realize molecular-colloidal organic-inorganic composites formed via multi-scale self-assembly in dispersions of anisotropic inorganic nanoparticles in liquid crystals [1,2]. These composites are pre-engineered to exhibit novel plasmonic, luminescence, photon-up-converting, and other unusual optical properties controlled by low-voltage fields and light itself. The lecture will conclude with a discussion of a new breed of potential applications of liquid crystal colloids.
