摘要：
Dy3+ doped Boro. tellurite glasses were prepared by following melt quenching technique with the chemical composition (69-x)H3BO3+xTeO(2)+15Mg(2)CO(3)+15K(2)CO(3)+1Dy(2)O(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) over bar and delta), Judd-Ofelt intensity parameters (Omega(lambda), lambda = 2, 4 and 6). The Y/B ratio has been discussed from the luminescence spectra for the excited states corresponding to F-4(9/2) -> H-6(11/2), H-6(13/2), and H-6(15/2) transitions. The structural and optical properties corresponding to the compositional changes are discussed and reported.
