Fluorotellurite Glasses

Sažetak
Novel fluorotellurite glasses were studied as candidates for fabricating mid-infrared optical fiber lasers. The thermal and optical properties including refractive indexes, UV-Vis-IR and FTIR spectra are reported. Raman spectra were recorded in order to analyze the changes in the glass structure with increasing ZnF2 concentration. The effects of adding ZnF2 on the optical properties of the fluorotellurite glass system are also discussed. It is demonstrated that the addition of ZnF2 greatly increased the thermal stability of the glass. Adding ZnF2 also reduced the hydroxyl (OH) content of the glass resulting in lower optical absorption in the infrared region. In addition, with increasing of ZnF2, the glass absorption cut-off edge at around 400 nm shifted to shorter UV wavelength. Raman spectra were recorded in order to analyze the changes in the glass structure with increasing ZnF2 concentration. And they showed the increase of transformation of TeO3+1 to TeO3 structures.
