摘要：

The paper reports the use of La2O3 and ZrO2 co-doping as a composite sintering aid for the fabrication of Tm:Y2O3 transparent ceramics. Two groups of experiments were conducted for investigating the influences of composite sintering aids on the microstructures and the optical properties of Tm:Y2O3 transparent ceramics in contrast to single La3+ and single Zr4+ doped Trn:Y2O3. Samples with composite sintering aids could realize fine microstructures and good optical properties at relatively low sintering temperatures. Grain sizes around 10 mu m and transmittances close to theoretical value at wavelength of 2 mu m were achieved for the 9 at.% La3+, 3 at.% Zr4+ co-doped samples sintered at 1500-1600 degrees C. The influences of the composite sintering aids on the emission intensities and the phonon energies of Tm:Y2O3 ceramics were also investigated. Crown Copyright (C) 2011 Published by Elsevier Ltd.
