摘要
Transparent Nd:Y2O3 ceramics were produced by vacuum sintering. Their fundamental optical constants including optical transmittance, reflectivity, absorption coefficient, refractive index, extinction coefficient, and dielectric constant were evaluated. Scintillation characteristics including radio-luminescence and light yield under alpha (Am-241 5.5 MeV) excitation are reported as well. (C) 2011 Elsevier B.V. All rights reserved.
