  1. 1. Impact of nanoparticle plasmons on photoluminescense and upconversion processes in ZnO

    University essay from Uppsala universitet/Solcellsteknik; Uppsala universitet/Fysikalisk kemi

    Author : Axel Gudmundsson; [2023]
    Keywords : Photoluminescence; Upconversion; Plasmons; ZnO;

    Abstract : The increasing prevalence of glass windows in modern buildings has raised the demand for solar control windows that possess climate-appropriate properties. Glass windows made of abundant and low-cost materials which can both decrease the heating energy consumption as well as enhance the light climate indoors would sufficiently meet the goals of economical yet uplifting buildings.

    Abstract : To increase the survival rate from infectious- and noncommunicable diseases, reliable diagnostic during the preliminary stages of a disease onset is of vital importance. This is not trivial to achieve, a highly sensitive and selective detection system is needed for measuring the low concentrations of biomarkers available. READ MORE

  3. 3. Towards a tunable nanometer thick flat lens

    University essay from Uppsala universitet/Materialfysik

    Author : Hugo Laurell; Johan Hillborg; [2018]
    Keywords : Metamaterial; COMSOL; Fano resonances; Surface plasmon polariton; Localized surface plasmons; Nanophotonics;

    Abstract : This report examines the cross sections of silver microresonators subjected to an incident light with different polarization. The microresonators had different geometries with and without broken symmetries. READ MORE

  4. 4. Photoemission electron microscopy of localized surface plasmons in silver nanostructures: Experiments and simulations

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Author : Robin Sutinen Svärd; [2015]
    Keywords : Photoemission electron microscopy; Localized surface plasmon; Ag nanocube; Ag nanoellipsoid; Finite-difference time-domain; Physics and Astronomy;

    Abstract : In this work, spatially resolved localized surface plasmons (LSPs) in individual silver nanocubes and nanoellipsoids are imaged with a photoemission electron microscope (PEEM). Using broadband laser pulses with photon energies below the work function threshold of the material, multiphoton photoemission (MPPE) processes coupled to the LSPs governs the strong enhancement of the plasmonic near-field detected in the PEEM.

  5. 5. Antibody-conjugated Gold Nanoparticles integrated in a fluorescence based Biochip

    University essay from Institutionen för fysik, kemi och biologi

    Author : Jonas Ljungblad; [2009]
    Keywords : Gold nanoparticles; Bioconjugation; Metal enhanced fluorescence; Localized Surface Plasmon Resonance; Ultra Violet Visible spectroscopy; Atomic Force Microscopy; Transmission Electron Microscope; Scanning Electron Microscope;

    Abstract : Gold nanoparticles exhibit remarkable optical properties and could prove useful in sensitive biosensing applications. Upon illumination gold nanoparticles produce localized surface plasmons, which influence nearby fluorophores and an enhancement in their fluorescence intensity can be observed. READ MORE
