UV laser induced gold nanoparticle fabrication dependent on initial film properties

Structure, Characteristics and Corrosion Behaviour of Gold Nanocoating Thin Film for Biomedical Applications

“…For that 100 nm Au thin film has more intensity/ peak than that of 50 nm. The XRD are in line with the results of researcher Schmidl et al 15 .…”

“…Another example is the ability to manipulate particle size and shape, as well as antibody conjugation on the surface for selective imaging and photothermal applications. Schmidl et al 15 found that laser parameters such as energy density and number of pulses influence the formation of gold nanoparticles on glass substrates induced by UV lasers. Furthermore, as the sputtering power increases, the microstructures and optical properties of the gold layers change.…”

Porous spherical gold nanoparticles via a laser induced process

“…A small number of gold layers used for experiments to generate porous NPs were additionally prepared using a DC sputter coater, and the deposition rate was kept at 0.3 nm s À1 . 32 The lm thickness of all individual lms was xed between 5 and 20 nm, respectively. The lm thickness ratio of Ag and Au was mainly varied between 1 : 1, 1 : 2, and 2 : 1 (Ag : Au).…”

Impact of thermal annealing and laser treatment on the morphology and optical responses of mono- and bi-metallic plasmonic honeycomb lattice

“…48 Short laser pulses are used to rapidly heat or melt, or even vaporize and ionize the materials. [49][50][51][52] Such fast and localized deposition of energy can result in local plasma generation. Followed by a fastcooling process, this method produces plasmonic nanoparticles without thermal equilibrium.…”
