Er 3 + green upconversion (UC) emission corresponding to the transition of S 3 2 4 ( H 11 2 2 ) I 15 2 4 is enhanced in a Er Dy -codoped Li Nb O 3 crystal compared with Er-doped Li Nb O 3 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 Dy 3 + ( F 9 2 4 ) to Er 3 + ( F 7 2 4 ) is 33%, which results in the enhancement of green UC emission. This energy transfer is advantageous for the Er 3 + UC emission sensitized by Dy 3 + , especially in a low-phonon-energy host matrix.
