  1. 1. Numerical simulations of ultrafast dynamics in plasmonic nanostructures

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Nils Henriksson; [2023]
    Nyckelord :Ultrafast nanophotonics; Three temperature model; Numerical simulations;

    Sammanfattning : Plasmonic effects in nanosized particles enhance the interaction between light and matter due to the localized surface plasmon resonance, with potential applications such as all-optical transistors and optical computers. Commonly, the dynamics of nanoparticles’ optical properties are assessed via pump-probe spectroscopy, where a plasmonic structure is exited by an initial laser, the pump. LÄS MER

  3. 2. Colloidal self-assembly of anisotropic gold nanoparticles

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Nyckelord :Self-assembly; Gold nanoparticle; Anisotropic; Nanobipyramid; Surface plasmon resonance; Självsammansättningar; Guldnanopartiklar; Anisotrop; Nanobipyramider; Ytplasmonresonans;

    Sammanfattning : The colloidal self-assembly of plasmonic gold nanoparticles (AuNPs) is of interest to utilize the plasmonic coupling effects that arise between nanoparticles. The enhanced properties of anisotropic AuNPs make them particularly attractive in self-assemblies. LÄS MER

  4. 3. Artificial photosynthesis - 4-Aminobenzoic acids effect on charge transfer in a photo catalytic system

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Simon Moberg; [2019]
    Nyckelord :artificial photosynthesis; aminobenzoic acid; charge transfer; plasmon; induced; plasmon induced; nanostructure; nanostructures; solar energy; nano particles; nano particle; artificiell fotosyntes; aminobensoesyra; laddningsöverföring; plasmon; inducerad; plasmoninducerad; nanostruktur; nanostrukturer; solenergi; nanopartiklar; nanopartikel;

    Sammanfattning : Artificial photosynthesis is used to harvest solar energy and store it in the form of chemical bonds. The system of interest in this study does this by splitting water into hydrogen and oxygen gas through a plasmon assisted process, collective oscillations from free electron gas. LÄS MER
