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<sup>3+</sup>) and rare earth ions (Eu<sup>3+</sup>) were synthesized and the glass transition temperatures and thermal stability parameters were determined using DSC measurements. X-ray dif...
