“…A decrease was observed in the fluorescent background and new bands appeared at 140, 281 and 376 cm − 1 . These bands are in good agreement with the Raman bands reported for orthorhombic PbO (Baleva et al . 1994).…”

Micro-Raman spectroscopy and the laser-induced transformation technique were used for systematic study of five coloured glazes on Saint John the Baptist (29 inch tondo), a majolica terracotta relief attributed to Luca Della Robbia and on permanent exhibit in The John and Mable Ringling Museum of Art. We suggest that S 3 − ions in a lead silicate matrix, called 'lead ultramarine', could contribute to the famous Della Robbia blue colour, in addition to the effect of Co atoms as suggested previously by Pappalardo et al. (2004). The original yellow glaze contains lead(II) antimonate. The green is a mixture of the yellow and blue pigments, the brown contains hematite, and the white glaze contains tin dioxide as an opacifier. The use of lead oxide as a main fluxing agent is confirmed by laser-induced micro-crystallization.

“…Figure 3 shows the Raman spectra of the nanorods. The Raman spectrum of the nanorods is exactly match with the α-PbO structure that was reported previously (Baleva & Tuncheva 1994;Wiechert et al 2005). As shown in Figure 3, the Raman spectrum of the PbO nanorods show a sharp, strong and dominant peak at 140 cm -1 corresponding to the A 1g mode of the Raman active mode, a characteristic peak for the motion of the lead atoms parallel to the c-axis.…”

“…On the other hand, the spectrum of the lowtemperature ␣ phase shows two sharp peaks at 82 and 148 cm −1 . 7 The strongest line in both phases is asymmetric and has a shape of a Fano line with a wing pronounced towards higher wave numbers. The nanotube spectrum at 50 kW/ cm 2 exhibits a strong radial breathing mode (RBM) at 167 cm −1 with two broad shoulders at about 150 and 180 cm −1 .…”

We investigated single-wall carbon nanotubes filled with lead oxide, PbO, by transmission electron microscopy and Raman spectroscopy. It is concluded that PbO crystallizes in the orthorombic phase forming nanowires inside the nanotubes. The positions of the PbO Raman lines are downshifted as compared to the bulk material as a result of the reduced dimensionality. As a consequence of the filling, nanotubes become sensitive to the laser irradiation. At higher laser power densities, they oxidize and the free PbO nanowires are left in the sample.
