Gold Nanoparticles by Nanopulsed Laser ablation(Nd-YAG)

Hay, I am Planning to synthesis gold nanoparticles by laser ablation (Nd-YAG nanopulsed Laser) in water as a part of my course project.I'm searching for how these factors - wavelength,pulse width, scanning time, fluence, repetition rate etc. , affect the size of the particles and efficiency or how to determine these factors according to what size we need ?Please help me See More

SOORAJ S replied to Mohammad Gultiaz Hassny's discussion laser ablation in liquids in the group NPs by Laser Ablation in Liquid
"I think you can use water .Gold colloid in water is really stable and less oxidation will take place.It is in the case of gold nanoparticles. Which nanoparticles you are planning to synthesis ? Which laser you are using ?"

synthesis of gold nanoparticles by LASiS

I am working on my course project titled " Laser induced assembly of gold nano particles into colloidal crystals". We are synthesising gold nano particles by nanopulsed laser(Nd-YAG second harmonic) ablation. How Laser parameters - wavelength,pulse width,fluence,repetition rate,scanning time affects the size and efficiency of the nanoparticles and which are the values for these factors to get maximum efficiency? we need to get nanoparticles have an average size less than 20nm.please help me.See More

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at editor@nanopaprika.eu

Dr. András Paszternák, founder of Nanopaprika
