We continue to talk about quantum dots and their application from various sides and publish it in different sources, because we ourselves are interested! Every day we learn about them something new and open up new opportunities in areas where they can be introduced to solve technological problems and for innovative discoveries!
We will remind what is quantum dot, tell about its main properties and share our selection of fresh articles and notes from IQDEMY holding. For your convenience, we collected the material on the links and divided it into topics.
What is a Quantum Dot (QD)?
Basically a Quantum Dot is a tiny little compound semiconductor particle that is only about 2-10 nm in size, or in other words 10-50 atoms. These particles have been achieved by treating semiconductor nanocrystals in a certain way, so that artificially synthesized nanocrystals are produced. Nanocrystal semiconductor particles differ in optical and electronic properties from that of larger particles.
Depending on the treatment of the nanocrystals, many different types of quantum dots can be achieved. In case of IQDEMY’s Quantum Dots, for example, when UV light or electricity is applied to a quantum dot, it will emit light in a certain visible spectrum. The color of light depends again on the size of the quantum dot. The smallest particles will emit violet color, the bigger the particles are, the light spectrum from violet to blue, green, yellow and red is covered. As the size of the Quantum Dots can be precisely determined in shape, size and material, different color frequencies are achieved. This opens up a host of applications in the security printing, brand protection industry and many other fields.
