Commercially available α-Al2O3 (99.99% purity, Taimei Chemicals, Japan) was processed as received (un-doped) and doped with Nd2O3 (99.99% purity, Alfa Aesar, USA). The powders were mixed to achieve doping levels (Nd3+:Al3+) of 0.25 and 0.35 at.%. The powders were mixed dry in an alumina mortar by hand for 20 min, which was followed by low-energy ball milling for 12 h with ultra-high purity (UHP, 99.99% purity) water as a dispersant. The slurries were sieved and centrifuged for 15 min at 3400 RPM. The powders were dried in a vacuum oven at 70 °C under a vacuum of 30 mm Hg for 12 h. Dried powders were subsequently planetary ball milled with UHP water at 150 RPM for 6 h. Finally, the powders were sieved and dried in air at 120 °C for 12 h and kept dry until consolidation.

Precursor materials were prepared from commercial powders corresponding to the stoichiometric compositions of (Nd 1 ) NdAlO 3 perovskite and (Nd 2 ) Nd 3 Al 5 O 12 garnet (Table 1).
Precursor coatings were thus prepared from the pure oxides Al 2 O 3 (Sigma Aldrich, 99.7%), Nd 2 O 3 (Alfa Aesar, 99.9%). The starting powder materials were milled in a Retsch 2000 Ball Mill (model MM2000, Resch, Haan, Germany) using an alumina grinding component, with isopropyl alcohol (PANREAC, chemical purity) as a liquid suspension medium with a solid content ranging between 62 and 65 weight %. The resultant suspension was deposited onto commercial 8 Â 10 Â 1 mm 3 polycrystalline alumina plates using the dip-coating method. The substrate was immersed into the suspension and extracted vertically at a speed of 10 mm s À1 . The coated plates were dried for a period of 48 h at room temperature before laser processing.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
