Reflection spectra of crystalline and vitreous modifications of GeO2 and SiO2 in the 5?50 ? region

Fictive temperature of GeO2 glass: Its determination by IR method and its effects on density and refractive index

“…The reflection peak for GeO 2 glass at 916 cm À1 in wavenumbers is known as the germania structural band from literature [3][4][5][6]. As can be seen in the paper by Venediktov et al, the vibrational spectrum for GeO 2 glass and SiO 2 glass exhibit similar spectra with peak wavenumbers shifted by the bond strength (k) and reduced mass (m) difference between Si-O and Ge-O bonds, t ¼ 1…”

“…It is expected that the same technique is applicable to germanium dioxide glasses since these glasses exhibit similar structural bands to those of silica glass [3][4][5][6]. This possibility was explored.…”
