Glass formation and the vibration spectra in the GeAsSI system

Abstract: A review is given of glass synthesis including the discussion of the area of glass formation in the quaternary GeAsSI system. Analyses of the probable glass structure are carried out according to the vibration spectra. The results obtained indicate that this system may be treated as quasibinary combination of (AsSI) x (GeS2)1−x type.

“…3a and b show the typical absorption spectra for the sample Ge2oAs~4S40Se~2I~4 whose thickness was 50 #m. It is obvious that a thickness of 50 #In enables the 90% transparency to be extended practically up to 850cm -~ where the vibrations related to As-S and As-I bonds became apparent. Absorption at 11 000 crn-l is not typical for the system but as in the case of previously investigated related glasses [4] it is the consequence of impurities (in principle it could be avoided by more accurate technological procedure). The absorption peak at 3500 cm -1 corresponds to the vibrations of the OH group [5,6], while that at 1600 cm-l corresponds to the vibrations of the H -O -H group.…”
