Synthesized ZnO NPs were irradiated with 50 MeV Li3+ SHI two fluences: 5 × 1011 and 1 × 1013 ions per cm2. The electronic and nuclear energy losses are found to be 15.61 keV μm−1 and 0.087 keV μm−1 in the range 206.1 μm for the range of the projectile ions of Li3+ at 50 MeV.
ABSTRACTWe report site-selective studies of the Zeeman splittings that are observed for magnetic fields up to 6.6T for different Eu incorporation sites in GaN. Utilizing resonant excitation with visible light, we are able to distinguish the site and find for one center (Eu1) a splitting into five components as expected for C3v symmetry. The corresponding g-values are 1.66 and 1.90. The two lines of another center Eu2 each split into two levels corresponding to g-values of 1.9 and 2.84. Most surprisingly a third center, for which only one line is clearly identified, a g-value of 6.16 is found which is larger than can be explained for a 7F2 purely ionic Eu state.
