Emission Mechanisms of Si Nanocrystals and Defects in SiO₂ Materials

Figure 4

(Figure 4 from [20]). Raman shift spectra for some of the samples as in Figure 3. Curves (a)–(d) correspond to the samples treated at 1050, 1100, 1150, and 1150°C (3 h), respectively. Curve (e) is from a SRO obtained from a mixture of hexamet and hexaet. A curve for a pure hexamet-based sample is also shown.
