Visible Laser Induced Fusion and Fragmentation of Thionicotinamide-Capped Gold Nanoparticles

Thionicotinamide-capped gold nanoparticles undergo fusion as well as fragmentation upon laser pulse excitation (532 nm). The aggregation effect which is induced by thionicotinamide also disappears following laser pulse excitation. The morphological changes induced by thermal and photochemical effect...

Description
Summary:Thionicotinamide-capped gold nanoparticles undergo fusion as well as fragmentation upon laser pulse excitation (532 nm). The aggregation effect which is induced by thionicotinamide also disappears following laser pulse excitation. The morphological changes induced by thermal and photochemical effects were found to influence the optical properties of these particles.
