(a) Standard and deoxygenated ZrO2 insulators. (b) Solid–liquid interface during the crystal growth of LZO using W crucible and deoxygenated insulator and as-grown LZO (W, Deoxygenated) crystal. (c) Powder XRD patterns of LZO (W, Standard) and LZO (W, Deoxygenated) crystals. Inset is BSE image of polished LZO (W, Deoxygenated) specimen. (d) XRC and Laue image of the LZO (W, Deoxygenated) crystal. (e) Polished LZO (W, Standard) and LZO (W, Deoxygenated) specimens before and after annealing. (f) Transmittance spectra of polished LZO (W, Deoxygenated) specimens before and after annealing.
