    Abstract:

    This paper presents a spectroscopic study of Er, Yb co-doped Y2O3 transparent ceramics with 20 at.% Yb3+ and varied Er3+ concentration (0.5 at.% to 5 at.%). Room-temperature absorption spectra and refractive indices were measured. Standard Judd-Ofelt analysis was applied and the intensity parameters were calculated. With Er3+ concentration increasing, Ω2 decreases from 5.41 to 3.36, Ω4 ranges from 0.96 to 1.29 and Ω6 ranges from 0.64 to 0.72. The spectroscopic quality factor X4/6 ranges from 1.46 to 1.88. The radiative lifetime of 4I13/2 manifold is longest in the Er, Yb co-doped Y2O3 transparent ceramic with 0.5 at.% Er3+ content. All suggest that the Er, Yb co-doped Y2O3 transparent ceramic could be a potential material for near-infrared laser application.
