Qu'est-ce (qui) est excimer - définition

EXCITED DIMERIC MOLECULE CONTAINING A NOBLE GAS
Exciplex; Excited Dimer; Eximer; Excimers; Excimer molecule

excimer         
['?ks?m?]
¦ noun Chemistry an unstable excited molecule which is formed by the combination of two smaller molecules and rapidly dissociates with emission of radiation.
Origin
1960s: blend of excited and dimer.
Excimer lamp         
  • Commercially-used 172 nm excimer lamp for printing industry
ULTRAVIOLET SOURCE
Wikipedia talk:Articles for creation/Excimer lamp; Excilamp
An excimer lamp (or excilamp) is a source of ultraviolet light based on spontaneous emission of excimer (exciplex) molecules.
Excimer laser         
  • The Electra KrF laser demonstrates 90,000 shots over 10 hours
  • The electra laser at NRL is a KrF laser that demonstrated over 90,000 shots in 10 hours.
TYPE OF ULTRAVIOLET LASER IMPORTANT IN CHIP MANUFACTURING AND EYE SURGERY
Exciplex laser; Excimer lasers; Eximer laser
An excimer laser, sometimes more correctly called an exciplex laser, is a form of ultraviolet laser which is commonly used in the production of microelectronic devices, semiconductor based integrated circuits or "chips", eye surgery, and micromachining. Since 1960s excimer lasers are widely used in high-resolution photolithography machines, one of the critical technologies required for microelectronic chip manufacturing.

Excimer

An excimer (originally short for excited dimer) is a short-lived dimeric or heterodimeric molecule formed from two species, at least one of which has a valence shell completely filled with electrons (for example, noble gases). In this case, formation of molecules is possible only if such atom is in an electronic excited state. Heteronuclear molecules and molecules that have more than two species are also called exciplex molecules (originally short for excited complex). Excimers are often diatomic and are composed of two atoms or molecules that would not bond if both were in the ground state. The lifetime of an excimer is very short, on the order of nanoseconds.
