| Outline of Final Research Achievements |
In the present project, we demonstrated two experimental techniques. First, we demonstrated a solid-immersion-lens (SIL) microscope to improve thel resolution and the detection solid angle. We experimentally showed that by using the SIL, the resolution and the detection solid angle were improved by a factor of 2 and 3, respectively. Second, we demonstrated nanometer-accuracy fluorescence microscopy of individual two-color emitters. Depending on the orientation of the transition dipoles of the emitters with respect to the focal plane, their spots were spheroids whose major axes tilted from the axial direction. When acquired with the axial uncertainty of a conventional fluorescence microscope (700 nm), the tilt due to the dipole orientation caused a lateral shift of 20 nm. Improving the axial uncertainty to 18 nm enabled visualization of these two emitters with a 1-nm accuracy. The technique is necessary to accurately determine the 3D position of multiple rare-earth ions in crystal.
