Figure 3

FT-Raman spectra of samples synthesized by PLAL of a Cu plate in (i) acetonitrile, (ii) propionitrile, and (iii) butyronitrile at different laser wavelengths of (a) 355, (b) 532, and (c) 1064 nm. Peaks at 1350 and 1590 cm−1 correspond to the D- and G-bands of the sp2 hybridized carbon, respectively. They were attributed to GC shells on the surface of spherical Cu NPs. The characteristic CuCN peak at 2170 cm−1 is indicated by (▪).
