“…Reflectance spectra of DLC:Cu films can be found in [92], while reflectance spectra of DLC:Ag were presented in [88]. In the case of DLC:Ag films grown by different physical vapor deposition based methods, a surface plasmon resonance related absorption peak is located in the 400-500 nm range [13,16,19,21,67,78,89,119,125,126]. However, in [127] the plasmonic peak of the absorption spectra of multilayer DLC/Ag films was reshifted to the 600-900 nm range.…”
