Abstract

This work shows the photoinduced shape conversion of spherical silver nanoparticles produced by laser ablation in liquids. A combination of blue and white LEDs was used as light source for the shape conversion. Photoconversion also used hydrogen peroxide as oxidizing agent of nanoparticles under different sodium citrate capping conditions. Rhodamine 6G was the molecule probe for assessing the influence of shape conversion in the efficiency of surface enhanced Raman scattering.
