Ag ions were implanted into single crystals of yttria-stabilized cubic zirconia (YSZ) at 1.5 MeV to a fluence of 2 x 10(16) ions/cm(2). After implantation, heat treatments were performed at 500, 900, and 1000 degrees C in air. The surface color tone markedly changed from brown to a beautiful violet after heat treatments. Scanning transmission electron microscope (STEM) observations revealed that Ag nanoparticles were formed when samples were heated at temperatures higher than about 900 degrees C. The absorption spectrum in the visible region was measured. A large absorption peak appeared at 510 nm after heating at 900 degrees C. The peak could be attributed to the surface plasmon resonance of Ag nanoparticles.
