摘要：

This paper reports on the preparation and spectral properties of europium (Eu3+) and terbium (Tb3+) ions doped cadmium lead boro tellurite (CLBT) glasses. For reference glasses, physical properties have been evaluated. From the [measurements of X-ray diffraction (XRD), glass amorphous nature of these [glasses has been studied. From the emission spectra of Eu3+: CLBT glasses, five [transitions (D-5(0) -> F-7(0), F-7(1), F-7(2), F-7(3) and F-7(4)) at 579, 591, 613, 652 and 701 nm are observed with lambda(exci) = 392 nm (F-7(0) -> L-5(6)) and in the case of Tb3+ : CLBT glasses, four emission transitions D-5(4) -> (F-7(6), F-7(5), F-7(4) and F-7(3)) are observed at 489, 543, 584 and 621nm respectively monitered with lambda(exci) = 376 nm (F-7(6) -> (5)G(6)).
