Abstract
AbstractIn this work we investigated the influence of reagents in the synthesis of triangular silver nanoprisms through direct chemical reduction. We identified the chemical role of each reagent, i.e. H2O2, poly(vinylpyrrolidone) (PVP) and NaBH4, by systematically varying one reagent concentration while keeping the concentration of other reagents constant. We also discuss the applications of nanoprisms in blinking suppression of single semiconductor quantum dots. In addition, we also investigated the synthesis of silver nanodiscs through the reconstruction of triangular nanoprisms using halide ions. The results from different halide ions presented the different face‐selective etching rates on the well‐identified facet in the silver nanoprism.
