Preparation of triangular silver nanoplates by improved light-driven seed growth method

Triangular silver nanoplates (TSNPs) have attracted much attention for their tunable plasmonic properties. In this letter, TSNPs have been synthesized by the improved light-driven seed growth method with only trisodium citrate (TSC) as both photoreducing reagent and capping reagent. By means of this high efficient method, TSNPs could be produced in high yield. As a kind of promising material, TSNPs will be used for chemical and biological sensing, and they can also be applied in optical limiters against high intensity laser pulse.

Automated summary

This letter presents an improved light-driven seed growth method for the synthesis of high-yield triangular silver nanoplates (TSNPs) using trisodium citrate (TSC) as the photoreducing and capping reagent. TSNPs exhibit tunable plasmonic properties and hold promise for chemical and biological sensing, as well as optical limiters.
