| Abstract: | This article reports on the optical characterization of Pr3+‐, Er3+‐ and Nd3+‐doped cadmium lead boro tellurite (CLBT) glasses prepared using the melt quenching method. The visible–near infrared (Vis–NIR) absorption spectra of these glasses were analyzed systematically. On measuring the NIR emission spectra of Er3+:CLBT glasses, a broad emission band centered at 1536 nm (4I13/2 → 4I15/2) was observed, as were three NIR emission bands at 900 nm (4F3/2 → 4I9/2), 1069 nm (4F3/2 → 4I11/2) and 1338 nm (4F3/2 → 4I13/2) from Nd3+:CLBT glasses and an NIR emission band at 1334 nm (1G4 → 3H5) from Pr3+:CLBT glasses at an excitation wavelength (λex) of 514.5 nm (Ar+ laser).
