Dy{sup 3+} doped Boro-tellurite glasses were prepared by following melt quenching technique with the chemical composition (69-x)H{sub 3}BO{sub 3}+xTeO{sub 2}+15Mg{sub 2}CO{sub 3}+15K{sub 2}CO{sub 3}+1Dy{sub 2}O{sub 3} by varying the tellurium dioxide content as (x = 0, 10, 20, 30 and 40 wt%). The structural and optical properties have been studied through FTIR, absorption and emission spectra. The UV-vis-NIR absorption spectra were used to calculate the oscillator strength, bonding parameters ({beta}-bar and {delta}), Judd-Ofelt intensity parameters ({Omega}{sub {lambda}}, {lambda} = 2, 4 and 6). The Y/B ratio has been discussed from the luminescence spectra for the excited states corresponding to {sup 4}F{sub 9/2}{yields}{sup 6}H{sub 11/2}, {sup 6}H{sub 13/2}, and {sup 6}H{sub 15/2} transitions. The structural and optical properties corresponding to the compositional changes are discussed and reported.
