Novel Multicomponent Titanate-Germanate Glasses: Synthesis, Structure, Properties, Transition Metal, and Rare Earth Doping
Novel multicomponent titanate-germanate glasses singly doped with transition metal (Cr(3+)) and rare earth ions (Eu(3+)) were synthesized and the glass transition temperatures and thermal stability parameters were determined using DSC measurements. X-ray diffraction analysis confirmed fully amorphou...

description | Novel multicomponent titanate-germanate glasses singly doped with transition metal (Cr(3+)) and rare earth ions (Eu(3+)) were synthesized and the glass transition temperatures and thermal stability parameters were determined using DSC measurements. X-ray diffraction analysis confirmed fully amorphous nature of the received samples. Their structural and optical properties were compared with germanate glasses without TiO(2). Correlation between local structure and optical properties in titanate-germanate glasses is well evidenced by FT-IR, Raman, EPR, and luminescence spectroscopy. In particular, luminescence spectra and their decays are examined for glass samples, where GeO(2) was partially substituted by TiO(2). |
