  1. 1. Advancing Upconversion Emissions for Biomedical Imaging

    Author : Haichun Liu; Lunds universitet.; Lund University.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; upconverting nanoparticles; luminescence; fluorescence; inverse problem; biomedical optics; biomedical imaging; photon migration; upconversion; tomography; saturation; Fysicumarkivet A:2014:Liu;

    Abstract : During the past decade, upconverting nanoparticles (UCNPs) doped with rare earth ions have become an important class of fluorescence contrast agents for molecular imaging, due to their unique properties. Their property of anti-Stokes luminescence, with both the excitation and emission wavelengths close to the optimal for biomedical imaging, has been extensively explored in various biomedical applications.

The other part being the continued development of photon time-of-flight spectroscopy, as well as exploration of new application areas of this method. READ MORE

  5. 5. Compact Soft X-Ray Microscopy Sources, Optics and Instrumentation

    University dissertation from Stockholm : KTH

    Author : Per Takman; KTH.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; soft x-ray microscopy; water window; compact; laser plasma; liquid jet; zone plate optics; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : This thesis describes the development of a sub-60-nm full-period resolution compact soft x-ray microscope operating in the water-window region (2.3-4.4 nm). Soft x-ray water-window microscopy is a powerful technique for high-resolution imaging of organic materials exploiting the natural contrast mechanism between carbon and oxygen, cf. READ MORE
