The Er 2 O3-Yb 2 O 3 codoped TeO 2 -Bi 2 O 3 -Na 2 O-Glasses along with addition of AgNO 3 in basic compositions glasses have been prepared by traditional melt quench method. Investigation of the synthesized glasses is done by DSC, XRD, and UV-Vis. spectroscopy. The glass transition temperature is observed by differential scanning calorimetry. The amorphous nature of the synthesized glasses is confirmed by X-ray diffractogram taken at room temperature. The fluid displacement method on the basis of the Archimedes principle was used to calculated density of prepared samples. The UV-Visible absorption characterizations have been done in the range of 200–1100 nm of synthesized glasses having different percentage of doping of Er 2 O/Yb 2 O 3 /AgNO 3 . The study of optical properties of the glasses such as the absorption coefficient ( α ), cut-off wavelength, forbidden energy band gap (Eopt), refractive index and Urbach Energy (E u ) have been done. The effect of Er 2 O/Yb 2 O 3 /AgNO 3 on optical properties is observed.
