抄録

An α-Al₂O₃ bicrystal doped with Cr³+ was fabricated by diffusion bonding at high temperatures. It was found that a ruby phase with approximately 200nm thickness was formed along the grain boundary. This thin phase shows Cr³⁺:Al₂O ₃-induced luminescence, confirmed by confocal micro-luminescence spectroscopy.
