About the prize

“The said interest shall be divided into five equal parts, which shall be apportioned as follows: /- – -/ one part to the person who shall have made the most important chemical discovery or improvement…”  (Excerpt from the will of Alfred Nobel.)

Chemistry was the most important science for Alfred Nobel’s own work. The development of his inventions as well as the industrial processes he employed were based upon chemical knowledge. Chemistry was the second prize area that Nobel mentioned in his will.

The Nobel Prize in Chemistry is awarded by the Royal Swedish Academy of Sciences, Stockholm, Sweden.

The Nobel Prize in Chemistry 2023

Moungi G. Bawendi, Louis E. Brus and Aleksey Yekimov are awarded the Nobel Prize in Chemistry 2023 for the discovery and development of quantum dots. These tiny particles have unique properties and now spread their light from television screens and LED lamps. They catalyse chemical reactions and their clear light can illuminate tumour tissue for a surgeon.

Nobel Prize in Chemistry

The Nobel Prize in Chemistry 2023 was awarded to Moungi Bawendi, Louis Brus and Aleksey Yekimov “for the discovery and synthesis of quantum dots.”

Independently of each other, Ekimov and Brus succeeded in creating quantum dots, and Bawendi revolutionised the chemical production.

Quantum dots now illuminate computer monitors and television screens based on QLED technology. They also add nuance to the light of some LED lamps, and biochemists and doctors use them to map biological tissue.
