In the course of study, 10 different MgGeO3:Mn2+ samples with different manganese 2+ ion concentrations were synthesized: 0 mol%, 0.1 mol%, 0.25 mol%, 0.5 mol%, 0.75 mol%, 1 mol%, 1.5 mol%, 2 mol%, 5 mol% and 10 mol%. The samples emit a good luminescence in the red spectrum diapason and can be excited by ultraviolet radiation and X-rays. Samples can shine for up to more than 10 hours after excitation. X-ray diffraction, excitation spectra, luminescence spectra, afterglow spectra, extinction kinetics and thermostimulated luminescence were measured for samples. The obtained results provide the basis for assessing the processes taking place in the materials and the effect that the concentration of admixture ions has on the luminescence. Perhaps in the future it will be possible to use magnesium germanate in medical diagnostic equipment, yielding a further improved insight into the human body. In this case, the results of the study will be useful for medical application.
