5. 4. Development of an Upconverting Nanoparticles Quantum Yield Measurement System

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Meng Li; [2016]
   Keywords : UCNPs; upconverting nanoparticles; QY; quantum yield; fluorescence; luminescence; Physics and Astronomy;

   Abstract : Fluorescence imaging is a growing biomedical technique; it can be used to localize the luminescent biomarkers inside the tissue. Lanthanide-doped upconverting nanoparticles (UCNPs) are promising luminescent probes for multiple applications in biophotonics. They allow acquiring autofluorescence-free recordings with high spatial resolution. READ MORE
