The major origin of the satellite vibration band in emission spectra is the stretching of the terminal groups, which can be confirmed by IR and Raman spectroscopic techniques.

Homogeneous glasses were formed in the Cr 2 O 3- TeO 2- B 2 O 3- SrF 2 system, up to 20 mol% Cr 2 O 3. For these glasses, IR and Raman spectral measurements were carried out in order to elucidate the local structure. The results showed that BO 3 and BO 4 are the main structural units of the glass system and the chromium ions are located in the network. It was evidenced the presence of TeO 3 and TeO 4 units as possible structural units in our glasses.

ABSTRACTGlasses in the Al2O3-B2O3-Fe2O3-Na2O-SiO2 system were produced at a temperature of 1150 °C, poured onto a metal plate and annealed. The nature of the structural units and their bonding in the structure were studied by infrared and Raman spectroscopic techniques. The structural network of all the glasses studied is built from major [SiO4] tetrahedra with 2-3 non-bridging oxygens (NBO). Incorporation of Fe2O3 offers a destructive effect in the glass network.
