  1. 1. Optimization and Characterization of Luminescent Materials for the ESS Proton Beam Imaging System

    M1-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Emelie Wiklund; Anton Järild; [2021]
    Nyckelord :Chemical Engineering; Luminescent materials; Cr-doped Alumina; Proton Beam Imaging System; ESS; Chemistry; Technology and Engineering;

    Sammanfattning : Spallation sources such as European Spallation Source (ESS) produces neutrons by bombarding high-energy protons onto the target wheel. To determine the location of the proton beam a Proton Beam Imaging (PBI) system will be installed. LÄS MER

  3. 2. Study of the Optical Properties of sp2-Hybridized Boron Nitride

    Master-uppsats, Linköpings universitet/Tillämpad optik

    Författare :Eduardo Antunez de Mayolo; [2014]
    Nyckelord :Spectroscopic ellipsometry; boron nitride; optical properties; materials characterization; III-V nitride semiconductors; cathodoluminescence; electron microscopy; Raman spectroscopy;

    Sammanfattning : Nitride-based semiconductor materials make it possible to fabricate optoelectronic devices that operate in the whole electromagnetic range, since the band gaps of these compounds can be modified by doping. Among these materials, the sp2-hybridized boron nitride has properties that make it a potential candidate for integration in devices operating in the short-wavelength limit, under harsh environment conditions, due to the strength of the B-N bond.

  4. 3. Dash

    Master-uppsats, Högskolan i Borås/Institutionen Textilhögskolan

    Författare :Marjan Kooroshnia; [2011]
    Nyckelord :thermo-choromic ink; photo luminescent color; smart textiles; aesthetic expression;

    Sammanfattning : This is a textile design project aim to make acommunication stage with smart colors (Thermo-­‐chromic leuco-­‐dyes and photo-­‐luminescent colors). Allthrough a research question has been designed. Theobjects, colors, and materials have been chosen basedon the inspirations from the stimuli. LÄS MER
