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 hållbarhetAbstract : 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 Aside from the overall increase in light output, replacing outdated monochromatic street lighting with light-emitting diode (LED) lights with a broad emission spectrum could raise this issue more.

3. Fabrication and characterisation of RGB LEDs based on nanowire technology
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : 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
