Nanobismuth: Fabrication, Optical, and Plasmonic Properties—Emerging Applications

Figure 2

Broadband dielectric function (ε = ε₁ + iε₂, black) of bulk Bi together with literature data, showing their broad dispersion. The origin of these data and the reasons behind their dispersion (mostly in relation with the sample quality) are discussed in [34, 35]. Reprinted with permission from American Chemical Society.
