Abstract

To study the effects of temperature, wavelength, laser energy, and repetition of pulsed laser on the silver nanoparticles. The laser induced photoacoustic technique has been used to study photoacoustic properties of silver nanoparticles. The study found a direct correlation between the wavelength and the concentration of the photoacoustic signal. Moreover, an indirect correlation was predicted between the temperature and concentration of the photoacoustic signals. The laser energy was found out to be 355 nm at a constant repetition rate of 2 Hz and the repetition rate of 2 Hz was also selected for the entire measurements. The photoacoustic properties of silver nanoparticles were significantly affected by wavelength, temperature, repetition of pulsed laser, and input energy as predicted by the data collected from the study.
