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.

Sure, This method is very interesting and contains a lot of unique characteristics, and you will enjoy and learn a lot of physics.
I hope all of the members in this group start to discus with us this wonderful phenomena.
Yes, Ayman. The mechanism and new phenomena, the modification of this method are interesting topics, and need to be studied.
But, as a method, how to attract long-term attention? I think the works in this field should demonstrate the advantages and unique characteritics of this method, compared with other methods.
Otherwise, as a very small research direction, it will gradually disappear!
