The Effect of Microwave Irradiation on the Laser-generated Ag-TiO2 Compound Nanoparticles

The pulsed laser ablation technique in liquid solutions is a promising method for generating nanoscale materials due to its chemically clean and simple synthesis process. This study generates spherical Ag-TiO2 compound nanoparticles (CNPs) through pulsed laser ablation, a picosecond (ps) laser, in deionized water. Then the spherical shapes of the CNPs are changed to rod-like shapes using microwave (MW) irradiation in an ordinary MW (continuous- CW) machine at 700 W for 3.5 min. The effect of MWs on the CNPs is investigated. Before and after MW-irradiation, the samples are characterised using ultraviolet-Vis Spectrometer, transmission electron microscope, and scanning electron microscope machines. The results show that the spherical shape of the nanoparticles was changed to rod-like shapes after MW irradiation. Their nominal dimensions range from 50–70 nm to 150–700 nm in width and length, respectively. Changing the morphology of the nanoparticlesis important for various applications.
