Abstract

Aim: To assess the photo-acoustic techniques for the calculation of size, distribution, shape and phase of silver nanoparticles. Methodology: The silver nanoparticles were synthesized by sodium borohydride (NaBH4) and silver nitrate (AgNO3). Nine samples were prepared with varying concentrations and the changes in their properties were studied. Results: The shape of the silver nanoparticles was found to be spherical in shape. The average size of the silver nanoparticles was calculated to be 4-27nm. The results suggested that the particle size was decreasing with increase in the concentration of the silver nanoparticles. The strongest peak was obtained at 392nm which corresponds to the concentration C1. The absorption peak was found to be shifting towards the longer waves with the decrease in concentration. The XRD analysis revealed that the silver nanoparticles corresponding to all concentrations possessed crystal cubic structure. Conclusion: The silver nanoparticles were being extensively used in various applications due to their unique physical properties.
