  1. 1. In situ X-ray diffraction studies of vertically aligned CsPbBr3 nanowire arrays

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Jesper Larsson; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The past decade has seen a great interest in the development of metal halide perovskite materials for use in photo-optical devices, due to the excellent photo-optical properties of these materials. The primary limitation to industrial adoption, and the subject of much research, is the susceptibility of these materials to degradation from exposure to various factors such as air, heat and moisture.

  3. 2. Study of luminescent and energy properties of CsPbBr3 and CsPbI3 nanoplatelets

    L3-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Taddeo Salique; [2022]
    Nyckelord :quantum confinement; nanoplatelets; CsPbBr3; CsPbI3; semiconductor; exciton; perovskite nanocrystals;

    Sammanfattning : Halide perovskite semiconductor nanocrystals have been studied a lot recently because they allow a precise control over the entire visible emission spectrum and as a result, the possibility of a variety of light-emitting applications. In this study, cesium lead bromide CsPbBr3 and cesium lead iodide CsPbI3 nanoplatelets of 3, 4 and 5 monolayers (ML) have been synthesized. LÄS MER

  4. 3. Optical characterisation of AAO/CsPbBr3 perovskite nanocomposites

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Klára Nováková; [2021]
    Nyckelord :perovskite; scintillator; optoelectronics; semiconductor; X-ray detection; Physics and Astronomy;

    Sammanfattning : Direct bandgap metal lead halide perovskites offer promising optoelectronic properties desirable in a wide range of applications including photodetection. However, the incomplete and poor understanding of the photophysical processes taking place in these materials, along with their poor stability, is the bottleneck for optimisation and further development of metal halide perovskite devices.

  5. 4. Investigation on Stability of Cesium Lead Bromide quantum dots

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Lina Le; [2016]
    Nyckelord :kemisk fysik; chemical physics; Chemistry;

    Sammanfattning : Monodisperse colloidal quantum dots of fully inorganic cesium lead bromide CsPbBr3 are synthesised at two distinguished temperatures (120 and 180oC) using inexpensive commercial precursors. The stability of these quantum dots is studied under three different conditions by measuring absorption as well as photoluminescence as functions of time. LÄS MER
