Optical and Electrical Properties of Yttria Stabilized Zirconia (YSZ) Crystals

摘要

Optical transition spectra (lambda = 0.3-50 micrometers) and dc conductivity (25 degrees-1000 degrees C) data were obtained on YSZ single crystals commercially grown by the skull melting process. The crystals were doped with up to 2.0 wt% rare earth (Ce, Nd, Er, Pr) and transition (Mn, Fe, Cr, Ni) metal ions, and a few were annealed. Dopant effects were most pronounced in the visible region, but were evident throughout much of the spectral range. Annealing and dopant ions Ce and Er showed significant absorption effects attributed to the Ce(3+) ion. Electrical conductivity was only marginally affected by doping. (Author)
