Eu{sup 3+} doped boro-tellurite glasses with the chemical composition (39-x)B{sub 2}O{sub 3}+30TeO{sub 2}+15MgO+15K{sub 2}O +xEu{sub 2}O{sub 3} (where x = 0.01, 0.1, 1, 2 and 3 wt%) have been prepared by following conventional melt quenching technique. Spectroscopic properties of the Eu{sup 3+} doped boro-tellurite glasses have been studied by recording the optical absorption and luminescence measurements. Through the optical absorption spectra, bonding parameters ({beta}-bar, {delta}) have been calculated to identify the ionic/covalent nature of the glasses. Judd-Ofelt (JO) analysis have been carried out using the luminescence spectra. The JO parameters ({Omega}{sub {lambda}}= 2, 4 and 6) were used to calculate the radiative properties for the {sup 5}D{sub 0}{yields}{sup 7}F{sub J} (J = 1, 2, 3 and 4) emission transitions of the Eu{sup 3+} ions. The change in optical properties with the variation of Eu{sup 3+} ion concentration have been studied and discussed with similar studies.
