Abstract

Red upconversion (UC) emission at 626 nm is obtained from a LiNbO ₃ crystal codoped with Er³⁺ and Eu³⁺ under 800 nm femtosecond laser excitation. Energy transfer from (²H _11/2,⁴S_3/2) levels of Er³⁺, which are excited by excited state absorptions, to ⁵D₁ of Eu³⁺ followed by cascade to ⁵D₀ nonradiatively leads to this red UC emission. The energy transfer efficiency of ∼30% is obtained in LiNbO₃:Er³⁺(1.0 mol%),Eu³⁺(0.1 mol%). These initial experimental results indicate that the red UC emission can be obtained from Er³⁺/Eu³⁺ codoped system under diode laser excitation.
