Abstract

In this paper, we observed that in Er³⁺/Yb³⁺ codoped nanocrystals (NC), with the decreasing particle size and the increasing Yb ³⁺ concentration, the upconversion luminescence (UCL) of the red emissions of ⁴F_9/2 - ⁴I_15/2 gradually increased, while the green emissions of ⁴S _3/2/²H_11/2 gradually diminished under 980 nm diode laser excitation. In NC with lower Yb³⁺ concentration, both the red and green emissions result from a two-photon excitation. In NC with higher Yb³⁺ concentration, the red emissions result from a two-photon excitation, while the green emissions dominantly result from a three-photon excitation. A model was provided for explaining the above UCL phenomena.
