“…Figure 3 shows the absorption spectra of solutions of silver nanoparticles prepared from (300, 400, 500) pulses, energy (500 mL), and frequency (1 Hz) showing absorption peaks in the visible spectrum region (405, 408, 410 nm) [11,12] which is an indication of the formation of silver nanoparticles. Increasing the number of laser pulses leads to an increase in plasmon resonance and an increase in the absorption peaks.…”

In this study, the technique of pulsed laser ablation in liquid (PLAL) is used to prepare colloidal silver (Ag) nanoparticles in distilled water (D.W.). The optical properties and the synthesis of the nanoparticles are characterized by UV-visible spectrophotometer, photoluminescence (PL), infrared Fourier transforms (FT-IR), and transmission electron microscopy (TEM) measurement. The optical characteristics of (Ag) nanoparticles are investigated using (UV-vis) analysis on all colloidal samples, which reveal a large peak at wavelengths of (405-410 nm) for silver nanoparticles created using PLAL technology. The infrared Fourier transforms (FT-IR) study determines the functional groups of silver nanoparticles in D.W. The silver nanoparticles (AgNPs) have a spherical form, and their diameters range from 12 to 20 nm, according to the transmission electron microscopy (TEM) measurements. The photoluminescence (PL) data reveal two peaks, one in the visible region, which is responsible for the production of silver nanoparticles, and the other in the UV region, where the size of the nanoparticles grows as the number of laser pulses increases.
