Quantum dots belong to the nanotechnology category and can also play an important role in artificial intelligence, sustainability and Environment 4.0.
Quantum dots are tiny crystals that are only a few nanometres in size - that's about 10,000 times smaller than the diameter of a hair! They have very special properties because they are so small. Most importantly, depending on their size, they glow in different colours when exposed to light.
This makes quantum dots particularly popular in screens, 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 visualise specific substances in the body. Researchers are also working on using quantum dots to make solar cells even more efficient.
An illustrative 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 - making the picture appear much more vivid and natural. The same principle can also help to generate green electricity even more efficiently.
