The size and shape of it : The optical properties of Ag nanoplates can be precisely tuned in a wide range through a UV‐light‐induced reconstruction process in which the morphology of the nanoparticles is changed from thin triangular plates to thick round plates (see picture). This unconventional “backward tuning” strategy is a practical route to stable silver nanoplates that display a wide range of plasmon wavelengths.
