Abstract: The mobility of Na+ ions in Na3+xSc2(SiO4)x(PO4)3−x (0.1 < x < 0.8) was investigated by temperature-dependent 23Na NMR spectroscopy and relaxometry. These measurements are probing the local motion of the Na+ ions and give information about the average hopping rate of the ions and the activation barriers these ions have to overcome for single jumps. The results are compared with those obtained by impedance spectroscopy that is probing the long-range transport of the Na+ ions. A consistent picture is obtained with the fastest motion of the Na+ ions observed for the sample with x = 0.4.
