| Abstract: | The Eu3+ luminescent emission spectra of rare-earth titanate, titanate-stannate, stannate, hafnate and zirconate pyrochlores, A3+2B4+2O7, indicated that a linear relationship existed between the splitting of the 5D0 → 7F1 magnetic-dipole transition and the size of the cation present. Small A3+ cations and larger B4+ cations both produced a lattice with a lesser degree of deviation from Oh symmetry. |
