Fig. 2

a the effect of CAPAD temperature on the relative density of un-doped and samples doped with 0.25 and 0.35 at.% Nd. The inset is a picture demonstrating long range transparency. b XRD profiles of the starting Al2O3 and Nd-doped Al2O3 powders. For the 0.25 and 0.35at. % powders, there are peaks attributed to the Nd2O3 dopant as indicated by arrows. c XRD profiles of Al2O3 and Nd-doped ceramics. The un-optimized Nd-doped sample shows a clear secondary phase (indicated with an arrow). The optimized samples do not show signs of a secondary phase present. The inset on the right clearly shows a peak shift relative to an α-Al2O3 standard (dashed line) for optimized Nd:Al2O3
