Fig. 1: Crystal structure analysis of as-prepared Ba2LuAlO5.
From: High proton conduction in Ba2LuAlO5 with highly oxygen-deficient layers
a X-ray powder diffraction profile and b Rietveld pattern of as-prepared Ba2LuAlO5 at 22 °C (Rwp = 0.084). The red crosses, dark blue lines, and black dots represent observed, calculated, and difference intensities, respectively. Green ticks denote calculated Bragg peak positions of hexagonal Ba2LuAlO5.
