摘要

The effect of Zn²⁺ ion on the dopant occupancy and optical characteristic of Er³⁺ ion in Er/Zn-codoped LiNbO₃ crystal is reported. The intense 1.54 渭m and relatively weak green upconversion emissions are observed for Er (1 mol%)/Zn (6 mol%):LiNbO₃ crystal. The OH^{鈭?/sup> absorption and the time-resolved spectra show that the Zn2+ codoping decreases the threshold concentration of Er3+ ion in Er/Zn-codoped LiNbO₃ crystal. The experimental results here imply that the potential application of Er3+-doped LiNbO₃ crystal can be designed and optimized on the basis of the theoretical investigations.}
