Abstract

Here, we bring out an IR transmitting new optical glass based on TeO₂ added with AlF₃ and LiF, containing dual rare earth ions as the dopants with a purpose to examine their luminescence and also the decay times pertaining to a prominent transition of Eu³⁺ (⁵D₀ → ⁷F₂ at 615 nm) as a function of temperature both in the presence and absence of Nd³⁺ ions. The energy transfer rates (W_tr) critical distances (R₀)and transfer efficiencies (η_tr) have been evaluated based on the measured lifetime data of this glass.
