  1. 6. Direct measurement of fluorescence lifetime using high speed data acquisition

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Mattias Olsson; [2018]
    Keywords : Boot-strapped waveform averaging; fluorescence lifetimes; TCSPC; repetitive signal; Technology and Engineering;

    Abstract : Time-correlated single photon counting (TCSPC) is commonly used to measure the lifetime of fluorescence from dye molecules. In TCSPC, the sample is excited by a pulsed laser and the arrival time of each of the emitted photons at the detector relative to a trigger is recorded. READ MORE

    Keywords : Ultrasound Optical Tomography; Deep Tissue Imaging; Monte Carlo Simulation; Spectral Hole Burning; Physics and Astronomy;

    Abstract : Ultrasound Optical Tomography (UOT) is a proposed technique, which combines ultrasound imaging and optical imaging in a new way to detect, e.g. READ MORE

  4. 8. Copper-based Redox Systems for Dye-sensitized Solar Celles

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Rebecca Pernechele; [2017]
    Keywords : ;

    Abstract : In order to take on the challenge of the world energy issues, there is a necessity to identify alternative energy sources to the fossil fuels. The sun represents the most abundant source of energy, and one way to harvest it is by photovoltaic devices directly converting sunlight into electricity. READ MORE

  5. 9. 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

  6. 10. Fluorescence Lifetime Measurement using Time Correlated Single Photon Counting

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Kemisk fysik

    Author : Mohammad Bilal Akhtar; [2010]
    Keywords : Chemistry;

    Abstract : A time correlated single photon counting (TCSPC) setup is built to measure the fluorescence decay of samples, such as solar cell materials. TCSPC is a sensitive technique for measuring fluorescence decays on nanosecond time scale and longer. READ MORE
