“…One of the main drawbacks of glasses doped with tetravalent chromium is that their luminescence quantum yield is much lower than that of crystals. It was proposed [2,7,8] to develop a glass ceramic material-glass ceramics-to combine the advan tages of crystals (relatively high quantum yield) and glasses (fiber drawing technology). Glass ceramics is doped with Cr 4+ ions, which are incorporated into the crystalline Mg 2 SiO 4 phase (existing in the form of nanoscale crystallites).…”

“…Glass ceramics is doped with Cr 4+ ions, which are incorporated into the crystalline Mg 2 SiO 4 phase (existing in the form of nanoscale crystallites). The possibility of forming a transparent glass ceramics doped with tetravalent chromium in forsterite and LiGaSiO 4 crystals was shown in [7,8]. This material allows drawing optical fibers with a relatively small loss.…”

A technology for production of nano glass ceramic materials based on aluminosilicate glass doped with chromium oxide is proposed. A comparative study of the spectral luminescence properties of for sterite glass ceramics and single crystal doped with chromium ions is performed. It is shown that chromium ions are partially incorporated into the glass ceramics crystalline phase. The quantum luminescence yields of Cr 4+ ions in forsterite nano glass ceramics and single crystal are found to be close.
