Abstract (English)

Lanthanide-doped upconversion nanoparticles (UCNPs) have emerged as promising candidates for various biological applications since they can be excited with near-infrared light, which is characterized by minimal scattering and negligible background fluorescence excitation in tissues. Within this thesis, one of the main challenges of UCNPs is tackled: the low upconversion efficiency and thus low ...

Lanthanoid-dotierte Upconversion-Nanopartikel (UCNPs) haben sich als vielver-sprechende Kandidaten für verschiedene biologische Anwendungen erwiesen, da sie mit Nahinfrarot-Licht (NIR) anregbar sind, was zu einer minimalen Streuung und Hintergrundfluoreszenz im Gewebe führt. In dieser Arbeit wird eine der größten Herausforderungen von UCNPs behandelt: die geringe Upconversion-Effizienz und die ...
