Abstract
This article presents the influence of praseodymium or cerium ions on physicochemical properties of yttrium oxide. Pure yttrium oxide and yttrium oxide doped with Ce or Pr ions powders were obtained by arc plasma synthesis. As a result of arc plasma synthesis, transparent, dense, uniform samples were obtained. To examine the microstructure and morphology of the powders and samples X-ray diffraction and scanning electron microscopy were used. X-ray studies have shown the incorporation of additives in the crystal lattice of yttrium oxide. In the present research work, Raman and FT-IR spectra of arc melted Ce or Pr –doped Y2O3 ceramics were reported. The optical and optical-magnetic properties were investigated for application as an optical insulator. Optical properties of the bulk samples were conducted from 200 to 1100nm. The in-line transmittances of ceramics exceed 35% from the visible band to the near infrared band. The results of measuring Faraday effect indicated that additives significance improve Verdet constant (> 130°/Tcm).
