Fundamental optical constants of Nd-doped Y2O3 ceramic and its scintillation characteristics

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 α (241Am 5.5 MeV) excitation are reported as well.
