Abstract Highly reproducible, active and stable SERS substrates were prepared by a nanocluster deposition system. SERS studies were carried out on these substrates with R6G as a test molecule using near Raman resonant and off resonant laser excitation wavelengths. Our results show that Ag nanoclusters of average particle size of (157 ± 119) nm act as very good SERS substrates for the ultra trace detection of R6G with an AEF of 2 × 10 12 corresponding to a detection limit of 10 −16  M.
