Abstract:
The analysis of the unified series of single-phase Zn$_{2-2x}$Mn$_{2x}$SiO$_{4}$ samples ($x\le$ 0.2) has provided the possibility to determine the optimal dopant concentration $x$ = 0.13 for the maximum luminescence intensity. It has been established that the dominating mechanism of concentration luminescence quenching and excitation energy dissipation is the oxidation of some Mn$^{2+}$ activating ions and the growth of defectness in the luminophore due to this process Phosphors.
