    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Needa Athitaya Wicksell Chuainukun; [2021]
    Nyckelord :Photochemistry; Copper iodide complexes; Substituted pyridines; Thin films; Luminescence lifetime;

    Sammanfattning : This paper deals with 3-picoline, 4-picoline, 3,4-lutidine and 3,5-lutidine complexes of copper(I) iodide (CuI(3-pic), CuI(4-pic), CuI(3,4-lut) and (CuI(3,5-lut)). The experimental investigation was divided into several parts. Firstly, the synthesis and characterization of the compounds both as powder and as thin films. LÄS MER

    Sammanfattning : A strategic and diverse set of passivation methods for gallium arsenide nanowires wasstudied. Using a time-resolved photoluminescence setup at100 Kand300 K, the radiativerecombination of charge carriers was resolved on a picosecond time scale. LÄS MER

  5. 4. Time-Resolved Photoluminescence Studies of InGaP Nanowires for Improving the Internal Quantum Efficiency

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Författare :Lert Chayanun; [2017]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Semiconductor Nanowires are promising building blocks for advanced optoelectronic devices since their small diameter give rise to quantization effects. The small diameter also makes them susceptible to non-radiative recombination due to surface states. LÄS MER

  7. 5. Time-resolved study of charge photo-generation in polymer-based solar cells with low driving force

    Magister-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Paulius Baronas; [2014]
    Nyckelord :Organic polymer solar cells; BHJ solar cells; Charge photo-generation; Driving force; Time resolved photoluminescence; CT states; Physics and Astronomy;

    Sammanfattning : Organic polymer-based solar cells recently attracted much attention as an efficient and inexpensive light-to-electricity conversion solution. However, the mechanism behind charge generation processes in organic materials is still not fully understood due to complex nature of carbon-based compounds. LÄS MER
