Abstract

In this work, pulsed laser deposition has been used to produce Er³⁺doped lead-niobium-germanate thin films from Er³⁺doped 50Geo₂-25PbO-25Nb₂O₅ transparent glasses with an Er₂O₃ content in the 0.5-3 weight % range. In all cases, by pumping the ⁴I_11/2level of Er³⁺, the as deposited films are optically active showing at room temperature the ⁴I_13/2→⁴I_15/2emission centered around 1530 nm. The luminescence intensity increases as the Er³⁺content in the targets increases, whereas the opposite behavior is observed for the luminescence lifetime. The emission intensity and lifetimes of the 1.5 μm emission increase upon annealing.
