  1. 1. Correlating Photoconductivity with Photochromism in Oxygen-containing Rare-earth Metal Hydride Thin Films

    Master-uppsats, Uppsala universitet/Materialfysik

    Författare :Suraya Kazi; [2021]
    Nyckelord :Rare-earth metal hydride; Thin film synthesis; Thin film characterization; Optical properties; Electrical properties; Chemical composition; Photochromic materials; Photoconductivity;

    Sammanfattning : Scientists have recently discovered simultaneous photoconductivity and photochromism (i.e., optical switching upon light exposure) of oxygen-containing rare-earth metal hydrides (REMHO). A deep understanding of these extraordinary optical and electrical properties can open the door to advanced technological uses such as smart windows. LÄS MER

  3. 2. Electric Transport of Rare-earth Metal Oxy-hydride Thin Films

    L3-uppsats, Uppsala universitet/Materialfysik; Uppsala universitet/Tillämpad kärnfysik

    Författare :Suraya Kazi; [2021]
    Nyckelord :Photochromism; Photoconductivity; Rare-earth Metal Oxy-hydride; Electric Transport; Photodarkening; Yttrium Oxy-hydride;

    Sammanfattning : In this project, I investigate the photoconductivenature of photochromic rare-earth metal oxy hydrides (REMHO). Such materials have received increasingscientific attention since they show a color-neutralphotochromic effect that can be applied, e.g., in smartwindows or chromogenic devices. LÄS MER

  4. 3. A study of the photochromic effect in oxygen containing rare-earth metal hydride thin films and multilayer structures

    Master-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Sigurbjörn Már Aðalsteinsson; [2020]
    Nyckelord :;

    Sammanfattning : In this work, we have studied the photochromic response of several oxygen containing rare-earth hydride thin films (REHO, RE = Y, Nd, Gd, and Dy). Their chemical composition was characterized by an iterative multi-method approach based on ion beams, while the photochromic effect was measured by means of optical spectrometry. LÄS MER
