Direct Laser Synthesis of Ag Nanoparticles from Ammonia-alcoholic Solutions of AgNO3

Ag nanoparticles were synthesized as a result of irradiation of ammonia-alcoholic solution of AgNO3 with focused beam of Nd:YAG laser. The synthesized nanoparticles were characterized with SEM and EDX analysis, dynamic light scattering technique, absorption and luminescence spectroscopies. The average size of synthesized nanoparticles which is from 25 to 100 nm demonstrates a linear dependence on molar concentration of the used solution. Optical and luminescence properties of obtained Ag nanoparticles were demonstrated.
