Abstract
⺠We demonstrate that the NIR emission (754 nm) is associated with the 5F4/5S2â5I7 transition of Ho3+ ions without the contribution of the 5I4â5I8 transition for Ho3+/Yb3+ codoped Y2O3 and Gd2O3 bulk ceramics. ⺠Population saturation in the 5I7 energy level has been observed in Ho3+/Yb3+ codoped Y2O3, Gd2O3 bulk ceramics. ⺠We demonstrate the result, the NIR emission (754 nm) is associated with the 5F4/5S2â5I7 transition of Ho3+ ions, by the steady-state rate equations.
