| Outline of Final Research Achievements |
In this study, we tried to evaluate the individual particles directly using the transmission electron microscope with respect to the structure and optical properties of multilayered fluorescent nanoparticles. We succeeded in demonstrating that the optical properties of individual particles can be directly evaluated by electron energy loss spectroscopy using a monochromator. We found that the crystallinity of the nano region can be discussed by this approach, and the crystallinity of the shell layer is reflected in the fluorescence efficiency.
