Ion induced photon emission from solids

Creators

Description

Work at Georgia Inst. of Tech. on light emission from the impact of energetic ions on surfaces is reviewed. Excited states of backscattered particles, emission of continua, and radiation from molecules on the surface were studied. The relative emission coefficient for the 2P22D → 2p 2P0 BPI transition induced by B+ impact on Cu and Mo is shown as function of incident energy from 50 to 200 keV. It was found that ion-induced emission intensity increases when oxygen is admitted to the target region. An acceptable model for the origin of continua has been proposed but not absolutely confirmed. Chemical reactions on surfaces have been detected through characteristic emission. Ion-induced emission related to chemical behavior on the surface offers some potential for the study of chemical reactions on surfaces. 3 figures
