Brus equation emission energy Δ"E" = "hc"/λ, where c is the speed of light). This is useful for calculating the radius of a quantum dot from experimentally determined parameters. The overall equation is "E", "m"*, and "m"* are unique for each nanocrystal composition. For example, with CdSe nanocrystals: Brus equation The Brus equation can be used to describe the emission energy of quantum dot semiconductor nanocrystals (such as CdSe nanocrystals) in terms of the band gap energy "E", Planck's constant "h", the radius of the quantum dot "r", as well as the effective mass of the excited electron "m"* and of the
E. C. George Sudarshan floor?" E. C. George Sudarshan Ennackal Chandy George Sudarshan (also known as E. C. G. Sudarshan; 16 September 1931 – 14 May 2018) was an Indian theoretical physicist and a professor at the University of Texas. Sudarshan has been credited with numerous contributions to the field of theoretical Physics including optical coherence, Sudarshan-Glauber representation, V-A theory, Tachyons, Quantum Zeno effect, open quantum system and Lindblad equation, spin–statistics theorem, non-invariance groups, positive maps of density matrices, quantum computation among others. His contributions include also relations between east and west, philosophy and religion. George Sudarshan was born in Pallam, Travancore. Despite being
