Effects of laser fluence and liquid media on preparation of small Ag nanoparticles by laser ablation in liquid

Silver nanoparticles were successfully obtained by laser ablation method. The investigation of different conditions in synthesis was performed. Correlation between fluence and liquid medium on concentration was evidenced. •High laser fluence values of the order of thousand Joules/cm2 were used. • Used conditions allowed producing AgNPs with different sizes from 2 to 120 nm.This work was supported by the project NORTE 01-0145_FEDER-000018 and by project UID/EEA/04436/2013, by FEDER funds through the COMPETE 2020 - Programa Operacional Competitividade e Internacionalizacao (POCI) with the reference project POCI-01-0145-FEDER-006941.
