Abstract

The enhanced intensity and lengthened lifetime of 1.54 μm emission were observed for Er:LiNbO₃ crystal codoped with Zn²⁺ ions. The ZnO codoping led to the reduction of the green upconversion emission in Er:LiNbO₃ crystals. The decay trace of the ⁴S _3/2→⁴I_15/2 was obviously nonexponential for Er:LiNbO₃ codoped with 0 and 3 mol. ZnO, but became exponential for one codoped with 6 mol. ZnO. The OH^- absorption spectra showed after codoping with Zn²⁺ ions, the OH^- absorption peaking position shifted from ∼3495 to 3484 cm^-1, and the absorption cross section decreased. These spectroscopic characteristics suggested that the improvement of 1.54 μm emission was attributed to the reduction of Er ³⁺ cluster sites.
