Mathematical modeling of spectral selective absorption and reflection of light by metal-dielectric composites

Coloured metallic shine associated to lustre decoration of glazed ceramics: a theoretical analysis of the optical properties

“…8 shows the experimental spectrum of the blue metallic shine. We note a reflectance band at 395 nm, which is not assigned to a type of colloids reflectivity [15][16][17]. We also observe in Fig.…”

“…7 shows the experimental spectrum of the orange metallic shine. There is a reflectance enhancement from 560 nm, which is not comparable to a well-known reflectance band [15][16][17]. We cannot ascribe this feature to any type of colloids.…”

“…1(b) is the reflection spectrum of a golden-yellow metallic shine. It shows a band at 625 nm, which corresponds to the reflection of light by nanosize-Cu 0 -colloids [15]. Fig.…”

The role of copper and silver in the colouration of metallic luster decorations (Tunisia, 9th century; Mesopotamia, 10th century; Sicily, 16th century): A first approach

“…In the future, we will use the reflectivity of the Cu°and Ag°colloids to explain the appearance and the colour of the metallic reflection, because the bands in the coloured metallic reflection spectra correspond to the reflection of light by these metallic colloids. [17][18][19] From these data, we will try to develop a theoretical model to explain the coloured metallic reflection.…”
