| Popis: | The analysis of the unified series of single-phase Zn2 – 2xMn2xSiO4 samples (x ≤ 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 Mn2+ activating ions and the growth of defectness in the luminophore due to this process Phosphors. |
