Abstract

(Figure Presented) A pHunction of pH: The silver nanoprism fusion process can be turned on and off as a function of the pH value during photochemical synthesis. With appropriate pH regulation (see TEM images, middle and right), one can achieve excellent control over the nanoprism edge length with a fixed 10-nm thickness and the corresponding plasmon bands, which span the visible and NIR range (see extinction spectra, left).
