Obtaining and Crystallization Pecularities of Antimony Containing Chalcohalogenide Glasses

Optical properties and local structure of (As2S3)100-x(SbSI)x glasses

“…The latter can be attributed to appearance of crystalline antimony sulfoiodide [12]. This conclusion is confirmed by the results for the Raman spectra and the crystallograms of the glass ceramics [5,11]. The crystallograms for the annealed glasses in the temperature region T g ÷ T с manifest reflexes which coincide satisfactorily with the lines available for the polycrystalline SbSI and their Raman spectra contain sharp bands at 108-110, 138-140 and 318-320 сm -1 .…”

“…Somewhat different behaviour of the spectral dependences of the absorptions edge for the (As 2 S 3 ) 100-x (SbSI) x (50 ≤ х ≤ 90) glasses is found at T > T g . The value of T g = 370 K correlates with that for these glasses specified from the DTA curves obtained for the heating rate of 3 K/min (370-430 K [11]). …”

Raman spectroscopy and X-ray diffraction studies of (GeS2 )100-x(SbSI)x glasses and composites on their basis

“…In addition, it was found that the maximum temperature of the first effect of crystallization of (GeS 2 ) 100-x (SbSI) x glasses (50 ≤ x ≤ 90) weakly depends on the composition, and it is within 395-405 K. At these temperatures, crystalline inclusions of antimony sulphoiodide are formed in the glasses. The investigation results of (GeS 2 ) 10 (SbSI) 90 glass, annealed at 413 K for 1 h, using Raman spectroscopy and X-ray diffraction, confirm this conclusion [12,36]. Here, we present the data studies of the annealing effect on the structure of (GeS 2 ) 100-x (SbSI) x glasses with the content of antimony sulphoiodide 50 and 70 mol.%.…”

“…It has been shown that in the matrix of GeS 2 -SbSI glasses under certain thermal treatment SbSI crystalline inclusions could be obtained [10][11][12]. There is also a report on fabrication of antimony sulphoiodide crystalline inclusions in the matrix of (GeS 2 ) 100-x (SbSI) x glasses under laser beam treatment [13].…”

Structure of GeS2–SbSI Glasses by Raman Spectroscopy

“…But in the spectra for G50 and G40 samples, there are broad component bands centered at ∼315 and ∼290 cm −1 . From the previous studies on the structure of similar glass systems, 12 we find that with the addition of SbSI, especially the iodine, the sulfur in [GeS 4 ] units is readily replaced by iodine, leading to the formation of [GeS 4− x I x ] (1≤ x ≤4) units, or more generally the [GeS 3− x I x –SbSI] and [GeS 3− x I x –SbS 3/2 ] (1≤ x ≤4) units. Then, according to the expression for simple harmonic oscillator frequency: where f is the force constant related to bond strength, and u is the reduced mass.…”
