Power dependence of size of laser ablated colloidal silver nanoparticles
(© 2010 EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg, 2010-11)Silver nanoparticles have been produced by laser ablation of silver metal in nanopure water without any chemical additives. It has been observed that laser power has a control over the size of the nanoparticles. Increasing ... -
Radiative lifetime measurement of excited neutral nitrogen atoms by time resolved laser-induced breakdown spectroscopy
(© 2014 Royal Society of Chemistry, 2014-08)Lifetimes of the excited 2P2 (3P) 3p 4S3/2 level of a nitrogen atom corresponding to transitions to different lower states have been estimated by measuring the line intensity of a transition as a function of the delay time ... -
