SOORAJ S replied to Yasser Attia Attia's discussion LASER effect on nanoparticles"Thats a nice question.Actually i'm also searching for this.Generally,we can use pulsed lasers to reduse and increase the size of nano particles by varying the fluence(gold nano we can use Nd-YAG Q switched nano pulsed Laser) by focusing the…"
SOORAJ S posted a blog postGold 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 ?"
SOORAJ S added a discussion to the group NPs by Laser Ablation in Liquid
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
