Chromium activated powdery Mg2TiO4 was prepared using the oxides MgO and TiO2 with LiCl as a flux. The preparation was realized by two annealing processes one after another at 850 °C and 1400 °C for activated specimens and for samples without activator. The excitation spectra were measured at room temperature and 77 K. The difference in remission was investigated at 293 K for activated samples and specimens without chromium and also the difference in absorption for the same samples. The excitation-, remission- and absorption spectra show three peaks with a different behaviour if the activator concentration increases. Therefore the chromium luminescence centres in the Mg2TiO4 prove to be Cr3+-ions surrounded by six oxygen ions and chromium clusters respectively. The assumption of two different luminescence centres is supported by the results of the emission spectra. An energy transfer exists between these two types of centres and depends on the activator concentration.
