| 英文摘要 | In this work, the optical spectra emitted from the magnesia-alumina spinel (MgOAl2O3) surfaces induced by low energy, highly charged Xeq+ (6 <= q <= 20) ions were measured. In the collisions, the excitation process of sputtered atoms is discussed. In the analysis, a special attention was given to spectral composition of the optical radiation, dependences of lines intensity on projectile charge state (projectile potential energy), relative intensities of different lines, in which mainly present three features: (a) the results do not appear the spectral line of O particle. (b) there were no apparent increases in the photon yields of atomic Mg and Al lines with the increase of projectile charge state. (c) the ratios of spectral lines Al I 309.27 nm to Al I 396.41 nm of excited Al atoms ejected from the surface of insulator MgOAl2O3 increased with the increasing projectile potential energy, and both of the ratios of spectral lines Mg II 280.40 nm to Mg I 285.42 nm and Mg II 279.73 nm to Mg I 383.37, 383.98 nm increased with projectile potential energy increase. |
