We discuss charged particle emissions induced by low energy ion impact on non-metallic surfaces. It has been shown that the secondary electron emission yields(γ^-)observed in non-metallic targets are 2-3 times larger than those for metallic targets. As special phenomena in non-metallic targets, the Coulomb explosion phenomena, the incident ion flux dependence of γ^- and the target temperature dependence of γ^- are described. Furthermore, it is found that the secondary ion emission yields from nonmetallic targets are larger than those from metallic targets. It is also shown that the key mechanisms responsible for ion emissions from non-metallic surfaces induced by low energy ion impact are very different from those for metal targets.
