Quantum dots belong to the category of nanotechnology and can also play an important role in artificial intelligence, as well as sustainability and Environment 4.0.
Quantum dots are tiny crystals just a few nanometres in size – that's about 10,000 times smaller than the diameter of a hair! They possess very special properties because they are so small. Most importantly: depending on their size, they glow in different colours when illuminated with light.
This makes quantum dots particularly popular in displays, such as in certain televisions (QLED TVs): the colours are significantly more brilliant and energy-efficient than with conventional methods. Quantum dots are also used in medicine because they can specifically make substances in the body visible. Researchers are also working on making solar cells even more efficient with quantum dots.
A vivid example: Imagine you have a television with quantum dot technology. Here, these tiny particles ensure that red, green, and blue are displayed particularly clearly and brightly – the image appears much more lifelike and natural. The same principle can also help to generate green electricity even more efficiently.
