Optica Applicata
EN The UV and visible optical spectra (absorption, emission and luminescence excitation) of the Ho-doped CaO–Ga2O3–GeO2 glasses at room and liquid nitrogen temperatures have been investigated for the first time. The Ho-doped (CHo = 0.7 wt%) glass samples with garnet Ca3Ga2Ge3O12 (or 3CaO–Ga2O3[...]
EN An 27Al magic angle spinning (MAS) nuclear magnetic resonance (NMR) study of nominally pure and Cr-doped yttrium-aluminum garnet (Y3Al5O12 and Y3Al5O12:Cr) crystals is reported. It has been shown that the doping by Cr of the Y3Al5O12 crystals leads to the variation of the occupation by Al atoms both[...]

EN A series of undoped borate glasses: Li2B4O7, LiKB4O7, LiB3O5, SrB4O7, and LiCaBO3 of high optical quality and chemical purity were obtained from the corresponding polycrystalline compounds using standard glass synthesis under technological conditions developed by the authors. The glasses were obtain[...]
