Abstract

Here, we bring out an infrared transmitting new optical glass based on TeO2 added with AlF3 and LiF, containing dual rare earth ions (Eu3+,Nd3+) as the dopants with a purpose to examine their luminescence and also the decay times pertaining to a prominent transition of Eu3+ (D-5(0) --> F-7(2) 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 (Ro) and transfer efficiencies (eta(tr)) have been evaluated based on the measured lifetime data of this glass.
