Quantum dots are theoretically described as a point-like, or zero dimensional (0D) entity. Most of their properties depend on the dimensions, shape, and materials of which QDs are made. Generally, QDs present different thermodynamic properties from their bulk materials. One of these effects is melting-point depression.
Louis Eugene Brus[1] (born August 10, 1943) [2] is an American chemist, and currently the Samuel Latham Mitchell Professor of Chemistry at Columbia University. He is the co-discoverer of the colloidal semi-conductor nanocrystals known as quantum dots. [3] In 2023, he was awarded the Nobel Prize in Chemistry.
STOCKHOLM (Reuters) -Scientists Moungi Bawendi, Louis Brus and Aleksey Ekimov won the 2023 Nobel Prize in Chemistry for their discovery of tiny clusters of atoms known as quantum dots, widely used ...
In 1873, Maxwell published A Treatise on Electricity and Magnetism as a summary of his work on electromagnetism. In summary, Maxwell's equations successfully unified theories of light and electromagnetism, which is one of the great unifications in physics. [9] Maxwell built a simple flywheel model of electromagnetism, and Boltzmann built an ...
The 2023 Nobel Prize in chemistry has been awarded to a trio of scientists who worked to discover and develop quantum dots, used in LED lights and TV screens, as well as by surgeons when removing ...
The history of quantum mechanics is a fundamental part of the history of modern physics. The major chapters of this history begin with the emergence of quantum ideas to explain individual phenomena—blackbody radiation, the photoelectric effect, solar emission spectra—an era called the Old or Older quantum theories.

Silicon quantum dot. Silicon quantum dots are metal-free biologically compatible quantum dots with photoluminescence emission maxima that are tunable through the visible to near-infrared spectral regions. These quantum dots have unique properties arising from their indirect band gap, including long-lived luminescent excited-states and large ...
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. [1] Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Light is a type of electromagnetic radiation, and other forms of ...
