Influence of Sodium Borohydride Content on Triangular Silver Nanoprisms Dropped on Copper Hydroxide Nanowire-Based SERS Substrates.

In this work, surface-enhanced Raman scattering substrates with triangular silver nanoprisms (AgNPrs) dropped on copper hydroxide nanowires (CuOHNWs) were evaluated. AgNPrs were synthesized in colloidal solution using Ag nitrate, polyvinylpyrrolidone, trisodium citrate dihydrate, hydrogen peroxide, and sodium borohydride (NaBH). A set of five solutions with volume percentages from 0.
