Popis: In the present work, we studied the structural and optical properties of zinc-titania tellurite glass (75-x)TeO2-20ZnO-5TiO2-xEr2O3 doped with erbium ion Er3+ (where mol % : x= 0 (host), 0.5, 1, 1.5). The reported glasses were synthesized using tradition melt quench method. The X-ray diffraction and thermal profile were utilized to study the amorphous nature of the mentioned glass. Optical absorption UV-Visible-NIR spectra were measured for optical energy gap and Er3+ absorption bands analysis. Both visible and near infrared luminescence were performed at room temperature using 980 nm laser diode excitation where the optical transition mechanism of the Er3+ in the glass is finally proposed. Broad luminescence in the present glass suggests its potential for broadband optical application.
