Upconversion emission efficiency of Tb3+-Yb3+ codoped glass

Abstract

The upconversion quantum efficiency and power-conversion efficiency in Tb3+-Yb3+ codoped glass have been investigated theoretically by the cooperative sensitization rate equation model. Both efficiencies exhibited linear relations with pump-power density and decreased with Yb3+ concentration. It was found that the ratio of quantum efficiency to power-conversion efficiency is constant (0.56) and independent of pump-power density and Yb3+ concentration. The theoretical predictions were confirmed by the experimental results measured by an integrating sphere system. The absolute upconversion efficiency was estimated to be on the order of 104 in the pump-power density range of 4096W/cm2.
