ResumoAbsorption and emission spectra are given for Yb3+-doped Y2O3,Lu2O3 and Gd2O3 at room temperature. Y2O3 and Lu2O3 as close cubic matrices, show Yb3+ similar spectra different of Yb3+ in Gd2O3 monoclinic structure. Here, we use a new method to study and optimize the main spectroscopic properties with only one concentration gradient sample. Finally, assignments of Yb3+ Stark levels and Raman vibrations in Y2O3,Lu2O3 and Gd2O3 single crystal are given.
