✦ Synopsis

Phdspfiorescence a&excitation spectra hate been measured of Fe3*-doped LiAIsOa. &NaA102, Na-silicate glass and crystalIine alumina-silicates. All excitation spectra fit quite well the Tanabe-Sugano diagam for a high spin d5 configuration. The expected tetrahedial site symmetry of Fe3+in the host lattices and the value of the crystalline field parameter are strong evidence for phosphorescence of Fe3+. Ions in tetrahedral oxygen coordination, A shark zero-phonon t&n&ion has been observed in the Iow temperature phosphorescence and excitation spectra qf the ordered phase of LiAlsOa. In a few recent publications [ 1,2] it has been ',_ .
