The 2023 Nobel Laureate in Chemistry is Muki Bawindi, and the winner of the 2023 Nobel Prize in Chemistry is Muki Bawendi. E. Bruce and Alexei Ekimov for discovering and synthesizing quantum dots. The prize money is SEK 11 million (about US $1 million at launch) and will be divided equally among the three winners.
Quantum dots are nanoparticles, tiny crystals with only a few thousand atoms, in which quantum effects begin to appear. In this case, they can be displayed by placing them in a colloidal solution, and they will take on different colors. These different colors are due to the size of the quantum dots and how tightly packed the electrons are in them. Smaller particles emit light with shorter wavelengths, and the particles become larger in turn, with wavelengths ranging from blue to red.
Although they are made of the same material, size is the key to changing their properties. Not only do they emit different colors, but they also affect their electrical and thermal properties and even their melting points will be different. The properties of these quantum dots are somewhere between semiconductors and discrete atoms or molecules used in electronic devices.
Many applications of these materials can be adjusted by changing their size. Interesting applications include use in specific photovoltaic installations, absorbing solar energy, and even as a biological dye for visualizing the vascularization of tumors.
More applications are currently being explored in the fields of LEDs, lasers, light sources, medical imaging, antibiotics, fast-charging electronics, and quantum computers.
When asked about the application of quantum dots, Muki Bawindi said: "I don't know what will happen in the future. This is an exciting area of research. ”
This makes the essay on scientific concepts more interesting and easy to understand.
