| Abstract Scope |
Near infrared light is known to be transparent for biological tissues. The authors have worked on the NIR biomedical photonics since 2005. Namely, it is worth using the NIR excitation light for luminescence application since visible light or shorter wavelength light is lost at the shallow depth within a millimeter. Rare-Earth doped Ceramic Nanoparticles (RED-CNPs) are known to be a good fluorescent material with the NIR excitation both for visible and NIR luminescence through upconversion and normal excitation processes. Thermal decomposition method is well-known to form ultrasmall CNPs. However, it also known that the luminescence of the CNPs are quenched in water. In this presentation, we will explain the mechanism of the thermal quenching of CNPs and introduce nano-luminescent micelle structure with the CNPs to have multiple functions for biomedical applications. |
