  1. 1. Investigation of sex-based differences in responses to artificial light of the greater waxmoth (Galleria mellonella)

    University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Author : Prasoon Singh; [2021]
    Keywords : Light pollution; Galleria mellonella; warm-white light; moths behaviour; attraction;

    Abstract : Artificial light at night (ALAN) is becoming a greater threat to nocturnal species. Aside from the overall increase in light output, replacing outdated monochromatic street lighting with light-emitting diode (LED) lights with a broad emission spectrum could raise this issue more.

  2. 2. Optical Characterization of Lignin Nanoparticles

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Kristoffer Linder; [2020]
    Keywords : lignin; nanoparticles; nanoparticle; optical characterization; optical properties; surface plasmon resonance;

    Abstract : Lignin is one of the main components of wood and plants that acts as a kind of glue providing mechanical strength. It is a main polymer component composed from three phenolic structures, i.e. p-hydroxyphenyl (H), guaiacyl (G) and syringyl (S) units. READ MORE

  3. 3. Fabrication and characterisation of RGB LEDs based on nanowire technology

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Patrik Olausson; [2019]
    Keywords : RGB LEDs; InGaN; GaN; nitrides; platelets; nanotechnology; Technology and Engineering;

    Abstract : The white light LEDs of today are usually based on a blue LED and a phosphor, converting the blue light to longer wavelengths. While these phosphor-converted LEDs are extremely efficient compared to incandescent light or fluorescent light, there is still plenty of room for improvement. READ MORE

  4. 4. Construction and Characterization of a Confocal Setup for Functionalization of Light Emitting Diodes and Laser Diodes Using an Amorphous Nonlinear Medium

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Hana Zeneli; [2018]
    Keywords : Characterization; Characterization Microscope; Microscope; Confocal; Amorphous Nonlinear Medium; Laser; Laser Diodes; Infrared Laser; Infrared; Optics; Nonlinear Optics; Nonlinear; White Light Emission; Infrared to White Light; Physics and Astronomy;

    Abstract : A confocal microscope is built to examine molecular powders, and in particular the (PhSn)_4S_6 cluster, that emits white light when irradiated with infrared laser light. The confocal microscope operating at long working distances is assembled and characterized. READ MORE

  5. 5. Light emitting diodes based on n-type ZnO nanorods and p-type organic semiconductors

    University essay from Institutionen för teknik och naturvetenskap

    Author : Raja Sellappan; [2008]
    Keywords : ZnO; ACG; organic; Inorganic; Polymer; nanorods;

    Abstract : The aim of this thesis work was to fabricate a hybrid LED using organic-inorganic ZnO materials. The goal of the project was to get an efficient white light emission from zinc oxide (ZnO) nanorods active layer. READ MORE
