La spectroscopie d’émission est un outil puissant pour obtenir des informations sur lesprocessus microscopiques dans un plasma de décharge hors-équilibre (décharge couronne)dans des milieux denses tels que le gaz supercritique à haute pression et les liquides. Lesobservations spectroscopiques de la lumière émise à partir d'une zone d'ionisation créée parune décharge entre une pointe fine et un plan sont utilisées pour caractériser l'environnementlocal des atomes ou des molécules émettrices. Les caractéristiques spectrales observablesétant sensibles à l'environnement immédiat de l'espèce émettrice, rend la spectroscopieoptique très utile pour l'étude du plasma hors-équilibre en fonction des paramètres du milieu(pression et température).Dans ...
