Abstract The emission spectra and the temperature dependence of the relative intensity of luminescence of three manganese activated titanate phosphors [Zn2TiO4, (Mg, Zn)2TiO4, Mg2TiO4] after optical excitation with radiation from 300–500 nm were measured for various temperatures above 4,2 °K. The luminescence of the Mn4+-centre is influenced by the cations (Mg2+ or Zn2+) of the lattice. The temperature dependence of the relative intensity of the luminescence depends on the excitation wavelength. The results are discussed and found to be in good agreement with those of aC-C-model which assumes two energy parabolas for the excited state.
