    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coherent Multidimensional Spectroscopy; quantum beating; quantum coherence; 2D electronic spectroscopy; 2D fluorescence spectroscopy; Compressed Sensing theory; CdSe QDs; LH2;

    Sammanfattning : Coherent multidimensional spectroscopy (CMDS) is the most complete nonlinear optical technique based on the interaction of multiple short laser pulses with matter. It has grown to play a significant role in studies of optoelectronic materials and pigment protein complexes. LÄS MER

  4. 3. Multidimensional Fluorescence Polarization Imaging of Single Light Harvesting Complexes

    Författare :Sumera Tubasum; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Light Harvesting Complexes; Single Molecule Spectroscopy; Polarization Spectroscopy; Exciton Dynamics; Spectral Disorder;

    Sammanfattning : This thesis presents my research journey in the Department of Chemical Physics,Lund University. Multidimensional fluorescence polarization imaging is used to study single LH2s. The method uses linearly polarized excitation light and the emission is detected through a polarizer. LÄS MER
