Abstract: (769 Views)
In the present work, pulsed laser deposition (PLD) of silver in open air is used to fabricate Ag nanoparticle (NP) films on the substrate without using flowing gas. The target was ablated by trains of nanosecond pulsed Nd:YAG laser beam. The deposited NP films on the substrate were characterized using energy dispersive x-ray spectrophotometry (EDS), high resolution transmission electron microscopy (HRTEM), and UV/Vis absorption spectroscopy. Surface plasmon resonance (SPR) characteristics of NPs were extracted from the data of UV/Vis spectrum. The effect of distance between target and substrate on absorption spectrum of NP film was investigated. The results show that it can significantly change the peak and bandwidth of absorption spectrum.
Keywords: Ag NP film, Pulsed laser deposition in flowless open air, Surface plasmon resonance, UV/Vis absorption spectrum.
