1. 1. Evaluation of Amyloid Fibrils as Templates for Photon Upconversion by Sensitized Triplet-Triplet Annihilation

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : Sharon Berkowicz; Helena Olsson; Henrik Broberg; [2017]
   Keywords : photon upconversion; sensitized triplet-triplet annihilation; anti-stokes emission; amyloid fibrils; whey protein;

   Abstract : In the face of global warming and shrinking resources of fossil fuels the interest in solar energy has increased in recent years. However, the low energy and cost efficiency of current solar cells has up to this date hindered solar energy from playing a major role on the energy market. READ MORE

3. 2. Nd-doped Upconverting Nanoparticles for Deep Tissue Imaging

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

   Author : Hugo Söderlund; [2014]
   Keywords : fluorescence imaging; Upconverting nanoparticles; biophotonics; Nd-doped comparison; Physics and Astronomy;

   Abstract : During the last decade, upconverting nanoparticles (UCNPs) doped with rare-earth (RE) ions have been extensively studied in the field of biophotonics. Due to their unique properties of anti- Stokes shifted luminescence and with excitation and emission wavelengths optimal for biomedical imaging, they have become an interesting class of fluorescent contrast agents.
