Structure and Spectral Luminescence Properties of (ZrO 2 ) 0.909 (Y 2 O 3 ) 0.09 (Eu 2 O 3 ) 0.001 Ceramics Synthesized by Uniaxial Compaction and Slip Casting.

The structure, phase composition and spectral luminescence properties of single crystal and ceramic specimens of (ZrO 2 ) 0.909 (Y 2 O 3 ) 0.09 (Eu 2 O 3 ) 0.001 solid solutions synthesized using uniaxial compaction and slip casting techniques have been compared. The ceramic specimens have been synthesized from crushed single crystal specimens of similar composition. It has been shown that the crystalline structures of the ceramic and single crystal specimens are identical and cubic. The ceramic specimens synthesized using different methods prove to have close microstructure patterns. The spectral luminescence properties of Eu 3+ ions in the (ZrO 2 ) 0.909 (Y 2 O 3 ) 0.09 (Eu 2 O 3 ) 0.001 ceramic specimens are similar to those of the single crystals with similar composition. The (ZrO 2 ) 0.909 (Y 2 O 3 ) 0.09 (Eu 2 O 3 ) 0.001 ceramic specimens prove to have uncontrolled Cr 3+ :Al 2 O 3 impurities due to the synthesis conditions.
