Ejection, excitation and decomposition of large clusters from the surface of group II, III and IV elements by excimer laser excitation

Abstract

Light emission and scattering are analyzed for the plume of vapor produced by laser excitation of the solid target of Group II, III and IV elements. Spectroscopic evidences suggest that the plume consists of microclusters of target elements. The size of microclusters is estimated to be 0.6 nm in diameter.
