Optical and Morphological Properties of Silver Nanoparticles Synthesis by Laser Induced Forward Transfer Technique

Various methods could be employed to synthesize nanomaterials. In this work laser induced forward technology was used to synthesize silver nanoparticles. Silver nanomaterials were tested using different measuring instruments such as UV–vis diffuse (DRS), Atomic Force Microscopy (AFM), and optical Microscope to characterize features such as the optical and morphological properties of these nanoparticles. AFM results show that when the laser energy of the pulsed Nd: YAG laser increases, the diameter and roughness of produced AgNPs will be decreased for the same number of pulses and the air cavity between donner and acceptor. Also, results show that when laser energy is (300,400) mJ, the AgNPs diameters are (95.76,88.44) nm and the roughness are (7,6) nm respectively. While, results show that as laser pulses increase, structure to be rougher for different laser pulses and constant laser energy at 300 mJ the same behavior will be found when the laser energy becomes 400mJ.Finally, results show that the reflectance peaks of Ag NPs increase by decreasing the number of pulses to a maximum value of 467 at 2 pulses.
