“…According to the systematic investigation data on the structure of alkali and alkali-earth borate glass containing less than 40 mol % of the modifying oxide obtained by IR spectroscopy [9][10][11][12][13], the absorption in the region of 600-800 cm 1 is due to deformation vibrations of the B-O-B bridges in the borate net work. The 800-1150 cm -1 region is commonly referred to as the asymmetric valence vibrations of B-Ø bonds in borate tetrahedrons, while the absorption bands in the third range (1150-1600 cm -1 ) are related to the asymmetric valence vibrations of the B-Ø and B-Obonds in the BO 3 borate triangles.…”

This paper considers the coordination state of boron and aluminum ions in barium aluminoborate glass with a constant ratio of BaO : B 2 O 3 = 0.5 and a variable ratio of Al 2 O 3 : BaO = 0-3. The dependence of the concentrations of boron and aluminum atoms with a variable coordination number on the Al 2 O 3 content was estimated by IR, 11 B and 27 Al NMR spectroscopy. The nonlinear nature of the obtained dependences was attributed to variations in the aluminum oxide properties. At a content of less than 30 mol % Al 2 O 3 serves pri marily as a network former, while an increase in the Al 2 O 3 concentration results in its higher modifying role in the studied glass.

A series of glasses composed of xB 2 O 3 -8Al 2 O 3 -(90 -x)Na 2 O-R 2 O 3 (x = 65, 70, 75, 80, 85; R = Dy 3+ , Tb 3+ , Sm 3+ ) were prepared through melt-quenching. Structural evolution was induced by varying the glass composition. Increasing the glass network former B 2 O 3 enhanced the luminescence of rare-earth ions, as observed in the emission spectra. The mechanism of the glass structural evolution was investigated by the NMR spectra analysis. The dispersant effect of the glass structure was believed to promote the better distribution of the rareearth ions in the matrix and reduced the concentration quenching between them. The relationship between the glass structure and its optical properties was established.

“…The XRD patterns of BCM05 and BCM20are shown in fig 1. The absence of Bragg's peak in the XRD patterns confirmed that the prepared samples are amorphous and homogeneous in nature [12], [13]. The vibrational modes of the borate glass network show the presence of three infrared spectral regions.…”
