“…It should be noted that nanophase formation here couples with the ability of the boron ion to exist in two different structural environment (trigonal and tetrahedral [1]) affecting the glass luminescence spectra. Such an effect was previously shown for potassium -alumina -borate glasses with manganese ferrite [2], iron ferrite [3], and copper chloride [4][5][6] nanophases formed as a result of glass annealing.…”

The paper presents the investigation of lithium-potassium-alumoborate glasses (0- 25 mol.% Li2O) doped by copper ions. The effect of glass annealing on the Raman scattering patterns is discussed. It is shown that such an annealing results in drastic changes in the Raman scattering patterns for the glass with 10 mol.%of Li2O: the band at 481 cm-1 conventionally attributed to boron-oxygen bonds in metaborate rings disappears, while a set of narrow bands at 1236, 1500, and 1783 cm-1 is observed. We consider one of these bands, 1783 cm-1, as being the identifier of the formed Li(Al7B4O17) nanophase, XRD analysis supported the above suggestion. The effect of newly formed nanophase on the luminescence spectra is discussed.
