Effect of halogen ions on the infrared absorption spectra of some glasses containing vanadium

The stretching vibrational mode of the Si-O bond in silicate glass can be observed in the frequency range from 800 to 1200 cm super(-1) in infrared absorption. It is known that the position of the band near 1100 cm super(-1) due to the vibration of the Si-O bond between silicon and bridging oxygen s...

Description
Summary:The stretching vibrational mode of the Si-O bond in silicate glass can be observed in the frequency range from 800 to 1200 cm super(-1) in infrared absorption. It is known that the position of the band near 1100 cm super(-1) due to the vibration of the Si-O bond between silicon and bridging oxygen shifts to the lower frequency or new bands appear in the lower frequency region owing to the breaking of the Si-O bond. Alkaline-earth aluminosilicate glasses of the general formula XMO-YA1 sub(2)O sub(3)-2SiO sub(2) containing 0.1 mol% Fe sub(2)O sub(3) were studied and a broad infrared absorption band between 1080 and 1120 cm super(-1) was obtained for all the glasses that had an X/Y ratio from 2.1 to 0.47. The aim of the present work is to throw some light on the structure of these types of glasses and possibly on the glass structure.
