I am working on green synthesis of silver nanoparticles. I am getting particle size beween 100 to 150 nm. I have increased the stirring speed up to 2000 rpm. Still I am unable to get particle size below 100 nm.

Reduce the concentration of your silver precursor by a factor of 100 or 1000.

You have to control the amount of reactants in you reactor especially during the mixing process..you can try micro-pump/syringe and reduce the flow of your reactant.
