Figure 2From: Self-assembled silver nanoislands formed on glass surface via out-diffusion for multiple usages in SERS applicationsAbsorption spectra of the samples. Curve 1, after the first anneal; curves 2 and 3, after 4 and 9 cycles of removal-anneal, respectively; curve 4, after 9 cycles of removal-anneal and final MIF removal; curve 5, after the first annealing and film removal.Back to article page
