摘要：
The main parameters of the ion-photon emission (spectral composition, quantum yield, the spatial distribution and the dose dependences of the radiation of sputtered excited particles) at the bombardment of sapphire (Al2O3) by ions Ar+ are considered in this work. It is shown that for sapphire there are an additional, compare with pure metal (Al), mechanism of formation of excited particles. Formation of excited particles flying away from the surface depends strongly on its physical-chemical state. The investigation of main parameters of IFE can be used to assess the degree of amorphization of the surface due to ion bombardment.
