  1. 1. Quantification using SERS on a colloidal substrate

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Kasper Eliasson; [2021]
    Keywords : SERS; spectrometry; nano technology; plasmonics;

    Abstract : This thesis explores the practical usefulness of surface enhanced Raman spectroscopy on a colloidal substrate for quantification of organic analytes in a water matrix. The method evaluated is very simple and accessible as it utilizes a commercially available hand held Raman spectrometer and citrate reduced silver colloid substrate. READ MORE

  3. 2. Spectroelectrochemical analysis of the Li-ion battery solid electrolyte interphase using simulated Raman spectra

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Edvin Andersson; [2020]
    Keywords : Lithium Ion Battery; Solid Electrolyte Interphase; Surface Enhanced Raman Spectroscopy; Density Functional Theory; LIB; SEI; SERS; DFT;

    Abstract : Lithium Ion Batteries (LIBs) are important in today's society, powering cars and mobile devices. LIBs consist of a negative anode commonly made of graphite, and a positive cathode commonly made from transition metal oxides. Between these electrodes are separators and organic solvent based electrolyte. READ MORE

  4. 3. Plasmonic Effect of Metal Nanoparticles Deposited on Wide-Band Gap Metal Oxide Nanowire Substrate

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Mojtaba Gilzad Kohan; [2017]
    Keywords : plasmonic particles; nano wires; wide band gap semiconductors;

    Abstract : The application of nanowires (NWs) in solar cells (SCs) is of great interest due to their new promising aspects established in nanoelectronics. Semiconductors associated with plasmonic metal nanoparticles (NPs) such as Silver (Ag), Gold (Au) and Copper (Cu), show enhanced performance in solid state light absorbing SCs owing to plasmonic characteristic of noble metal NPs.
