Fig. 4

LIF spectra from selected samples of glass support (in black) and the corresponding grisailles (in red). The bands refer as ODC indicates oxygen deficiency centres. The ions marked in red are only identified in the grisaille spectra, and the black ones can be identified in both grisaille and support glass. (a–f) correspond to LIF spectra of samples JC012, CG2, JC015a, JC010, LS05, LS03 representative of each chronology studied. Laser scattering: double wavelength of incident laser light
