Abstract

The Nd³⁺ Cr³⁺ single and codoped lead silicate glasses (SiO₂-Na₂O-Sb₂O₃- PbO₂) were synthesized by means of fusion method. Their optical properties were studied by means of absorption and photoluminescence (PL), recorded at room temperature. The wear ⁴F_3/2 yields ⁴I_9/2 emission band centered at 890 nm observed in the Nd³⁺ single doped glasses was strongly enhanced in the Nd³⁺ and Cr³⁺ codoped glass. The effective mechanisms based on both direct donor-donor energy transfer processes assisted by localized phonons and energy cross-relaxation between donor-acceptor were proposed.
