  1. 1. Ultrafast Photoinduced Processes in Core and Core–Shell Quantum Dots for Solar Cell Applications “Tiny Crystals for Big Applications”

    Författare :Mohamed Qenawy; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum dots; core–shell; electron injection; hole injection; hole trapping; exciton migration; solar cells; ultrafast dynamics; time-resolved spectroscopy.;

    Sammanfattning : The balance between our demands of energy and the energy we are consuming is not in equilibrium anymore. Therefore, the search for other energy resources is indispensable. Sustainable energy sources offer the alternative to the fossil fuels. LÄS MER

  4. 3. Nanostructured carbon materials prepared by hole-mask colloidal lithography

    Författare :Hans Fredriksson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; HOPG; GC; Colloidal Lithography; Oxygen; RIE; Nanofabrication;

    Sammanfattning : Research and development of nanofabrication methods can be motivated both formanufacturing of commercially available products like micro electronic componentsand for development of model systems for fundamental and applied science. Thefabrication process developed during this work, hole-mask colloidal lithography(HCL), is primarily oriented towards the latter two, specifically for research in thefields of catalysis, nanoparticle plasmons, and bio- and fundamental physics.

  5. 4. Structure-Function Relationships in RuII Complexes with Unconventional Ligands: Photophysical and Photochemical Studies

    Författare :Joachim Wallenstein; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; structure-function relationship; spectral component analysis; photochemistry; RuII complexes; photoreaction; hole-transfer;

    Sammanfattning : The rich photophysics, photochemistry and electrochemistry of RuII complexes have attracted intense research interest in widely disparate fields. A large portion of the studied and applied complexes are derived from the archetypical [Ru(bpy)3]2+ (bpy is 2,2’-bipyridine), which absorbs in the visible region, displays a long lived (~1 μs), emissive metal-to-ligand charge transfer state, and shows reversible electrochemistry in both the ground and excited state.

  7. 5. Plasmonic Nanospectrocopy of Individual Nanoparticles - Studies of Metal-Hydrogen Interactions and Catalysis

    Författare :Svetlana Alekseeva; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; grain boundary; metal-hydrogen interactions; plasmonic sensors; single particle spectroscopy; palladium nanoparticles and nanocrystals; localized surface plasmon resonance; hole-mask colloidal lithography; nanocatalysts; shrinking-hole colloidal lithography; plasmonic nanospectroscopy; dark field scattering spectroscopy; nanoscale effects;

    Sammanfattning : Localized surface plasmon resonance (LSPR) is the phenomenon of collective oscillation of conduction electrons in metal nanoparticles smaller than the wavelength of light used for the excitation. Plasmonic metal nanoparticles are able to confine light to extremely small volumes around them, i.e. below the diffraction limit. LÄS MER
