• and characterization of silver nanoisland films (SNIFs) using pulsed laser deposition (PLD) and the evaluation of these films as potential surface-enhanced Raman scattering (SERS) substrates are reported. The SNIFs with thicknesses in a range of 4.7 ± 0.2 nm to 143.2 ± 0.2 nm were deposited under

• fabricated NPs can be controlled very well [13]. One of the less commonly used physical methods for the fabrication of SERS active gold and silver nanoisland films is pulsed laser deposition (PLD) [19][20][21][22][23][24][25]. In PLD, the materials are deposited on a substrate through laser ablation from a
