Effect of wavelength and liquid on formation of ag, au, ag/au nanoparticles via picosecond laser ablation and sers-based detection of dmmp

HIGHLIGHTS

• What: This study investigates the effects of input wavelength (1064 532 and 355 nm) and surrounding liquid environment (distilled water and aqueous NaCl solution) on the picosecond laser ablation on silver (Ag) gold (Au) and Ag/Au alloy targets. The investigations further focused on assessing the stability of a SERS substrate over 60 days. This study explored the impact of different Raman excitation wavelengths, specifically 325, 532, and 633 nm.
• Who: Sree Satya Bharati Moram et al. from the University of Hyderabad, ProfCR. Road, Hyderabad, Telangana, India have published the paper: Effect of wavelength and . . .
