【 摘 要 】

In this paper, Er:Y₂O₃ optical ceramics were fabricated and details of the synthesis were presented. The spectral–luminescent properties of Er³⁺:Y₂O₃ optical ceramics were investigated. The absorption and emission cross-section spectra were determined. The luminescence kinetics at near 1.6 µm was single exponential and the lifetime of erbium ⁴I_13/2 energy level was determined. In the frame of the conventional Judd–Ofelt theory, the emission properties of the energy levels of erbium ⁴I_13/2 and ⁴I_11/2 involved in laser operation at near 1.6 µm were calculated. The gain coefficient curves for typical values of the relative population of the upper laser level ⁴I_13/2 were presented. The composition and structure were studied using the SEM, XRD, FTIR spectroscopy, and X-ray computer tomography techniques.
