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.

Yes, LAL is a very interesting field. If someone can cite my related papers, i will be very glad, such as Composition/Structural Evolution and Optical Properties of ZnO/Zn Nanoparticles by Laser Ablation in Liquid Media, J. Phys. Chem. B 2005, 109, 18260-18266. (Cited 121) and Blue luminescence of ZnO Nanoparticles Based on Nonequilibrium Process: Defect Origins and Emission Controls, Adv. Funct. Mater. 2010, 20. 561-572. (Cited 48)
It is my pleasure to discuss some issues about LAL. What's the main problems in this field in your mind? Let's start from this topic.
Dear scientist,
Please any one having any thesis in the field of laser ablation in liquid environment shares this free link. :$
Hi Subhash Singh, I'd like this field too much and i'm in my way in M.Sc in synthesis of CdS, CdSe in liquid environment. so, may u help me about how to increase the hardness of the tablet to be able to resist the laser matter interaction more time?
