Nanoprisms, also referred to as nanoplates, are a class of two-dimensional structures with parallel top and bottom and a nanoscale thickness. As we known, nanoparticles’ shape is an important parameter, controlling their many physical chemical properties. Nanoprisms have attracted intensive attention because of their strong shape-dependent optical properties. Up to date, a variety of synthetic strategies, such as photochemical, thermal and biological routes, have been explored to prepare bulk quantities of metal nanoprisms.
