Upon heating, Mn atoms implanted into Na⁺- beta- alumina diffuse inwards and outwards with an activation energy of 0.96 eV, and substitute for Al³⁺ in the spinel layers of the crystal. For specimens annealed at 900℃, the optical absorption shows remarkable change in 190nm-400nm wavelength region. They fluoresce brightly green and a well- defined peak (at 525 nm) has been found in the radiative spectra.
