• Ion-induced luminescence of alumina was analyzed with a time-resolved spectroscopic method. By using a pulsed ion beam, we selectively observed the prompt and slow components in the total luminescence. The luminescence spectrum showed some broad peaks at 330 nm (F+ center), 410 nm (F center), 510 nm (F2 center), 560 nm (F22+ center).By observing prompt luminescence in detail, new emission bands have been identified in the wavelength range from 400 to 450 nm. Furthermore, the lifetime of each luminescence was successfully evaluated with single photon counting. The emission band at 400 nm was found to have a short lifetime of 1.9 ns. From the analysis of a slow luminescence component, it was observed that the emission band with a long lifetime appeared around the wavelength of 330 nm.
