Abstract

Er³⁺ green upconversion (UC) emission corresponding to the transition of ⁴S_3/2(²H_11/2) → ⁴I_15/2 is enhanced in a Er/Dy-codoped LiNbO₃ crystal compared with Er-doped LiNbO₃ under 800 nm femtosecond-laser excitation at room temperature. The upconversion mechanisms are proposed based on spectral, kinetic, and pump-power dependence analyses. The energy-transfer efficiency from Dy³⁺(⁴F_9/2) to Er ³⁺(⁴F_7/2) is 33%, which results in the enhancement of green UC emission. This energy transfer is advantageous for the Er³⁺ UC emission sensitized by Dy³⁺, especially in a low-phonon-energy host matrix.
