Effect of Different Ablation Time of ns-pulsed Laser on the Synthesis of Silver Nanoparticles in Liquid

Abstract

In the present report, we have studied the effect of nanosecond pulsed laser irradiation time on the particle abundance, morphology, and optical properties of silver nanoparticles (Ag-NPs). High-resolution transmission electron microscopy, selected area diffraction pattern, and UV-visible absorption spectroscopy were used to characterize morphological, structural, and optical properties of the Ag-NPs. The prolonged laser irradiation above 60�min demonstrates the melting and diffusion-induced aggregation of Ag-NPs. The statistical evaluation of various particles under different irradiation durations reveals uniform and monodispersed particle distribution for only 60�min of ablation duration. � 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
