1. Optimization and Characterization of Luminescent Materials for the ESS Proton Beam Imaging System
M1-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : Spallation sources such as European Spallation Source (ESS) produces neutrons by bombarding high-energy protons onto the target wheel. To determine the location of the proton beam a Proton Beam Imaging (PBI) system will be installed. LÄS MER
2. Provenansstudie av detriala zirkoner från ett guldförande alluvium vid Ravlunda skjutfält, Skåne
Kandidat-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : 2014 höll Sveriges geologiska undersökning (SGU) tävlingen ”Mineraljakten” med syfte att engagera allmänheten och utöka förståelsen kring hur olika metaller och mineral används i vår vardag. Till tävlingen kom det in ett fynd av vaskguld från Skåne som premierades med fjärde pris för den ovanliga fyndplatsen. LÄS MER
3. High Accuracy Relative Luminescence Quantum Yield Measurements of Upconverting Nanoparticles
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/AtomfysikSammanfattning : The name Upconverting nanoparticles refers to a novel category of luminescence emitters that are capable of generating visible luminescence upon excitation with noncoherent and longer wavelength monochromatic near-infrared light, at excitation fluence rates as low as 1-103 W/cm2. This unique optical behaviour is of great interest to researchers as it could potentially allow for virtually autofluorescence free luminescence imaging of living tissue. LÄS MER
4. Development of an Upconverting Nanoparticles Quantum Yield Measurement System
Kandidat-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenSammanfattning : 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. LÄS MER
5. Three-Dimensional Quantitative Cerenkov Luminescence Imaging
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/AtomfysikSammanfattning : Cerenkov luminescence imaging (CLI) is an up-and-coming optical technique for in vivo imaging of beta-emitting radioisotopes. CLI relies on measurements of the Cerenkov radiation emitted when high-energy beta-particles travel through tissue. LÄS MER
