  1. 11. Synthesis and Characterization of Copper Halide Complex Materials

    Master-uppsats, KTH/Tillämpad fysikalisk kemi

    Författare :Hiroki Tomita; [2021]
    Nyckelord :Copper halide complexes; Coordination polymers; Photoluminescence; Bidentate ligands; Applications of thin films; Kopparhalogenidkomplex; koordinationspolymerer; fotoluminiscens; bidentata ligander; tillämpningar av tunna skikt;

    Sammanfattning : Energiförbrukning är ett hett ämne i världen idag, eftersom världens befolkning fortsätter att växa. Som ett resultat ökar också den globala energiförbrukningen snabbt och utsläppen av koldioxid därmed, vilket påverkar global uppvärmning och klimatförändringar. LÄS MER

  3. 12. Optical Study of Micro-Resonators with G-centers as an Active Medium

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Baptiste Lefaucher; [2021]
    Nyckelord :G-center; Silicon Photonics; Micro-Resonators Optics; Laser; Photo-Luminescence Spectroscopy; G-center; Kiselfotonik; Mikroresonatoroptik; Laser; Fotoluminescensspektroskopi;

    Sammanfattning : The G-center has recently been identified as the first deterministic single-photon punctual emitter isolated in silicon. This discovery is of great interest for largescale quantum technologies, due to the abilities of silicon in terms of integration and scalability. LÄS MER

  4. 13. 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.
