Abstract

Laser ablation of a silver target confined in distilled water allowed us to obtain silver nanoparticles. However, to have knowledge of their production by this method, common instruments for measurement of the silver concentration in a colloidal solution are employed, this is due to laser ablation and is usually considered a top-down physical approach in the synthesis of nanoparticles. In consequence, this research has suggested an alternative to know the silver nanoparticles production through theoretical considerations, which depends on laser parameters and intrinsic properties of a silver target. Theoretically, this result has given us a silver concentration around 0.029 mg ml^− 1 and from of transmission electron micrographs were obtained a size distribution, where it was fitted with one Gaussian peak, being the smaller sizes the most frequent. The mean peak was centered at 12 nm, having a nanoparticle mass of 7 × 10^− 18 g, and regarding a relation with the silver concentration, the nanoparticles production was around 4 × 10¹² nanoparticles ml^− 1.
