Abstract

The results of in situ investigations of the luminescence of a single crystal of Alumina (Al₂O₃) during irradiation by the ions 93, 245, 425, and 609 MeV Xe^q+ are presented. The spectra are measured at room temperature in the wavelength range of 200–800 nm. The threshold value of electronic stopping power (S_e) for luminescence in Al₂O₃ is estimated to be about 18.3 keV/nm. In the spectra, the observed bands at 336 nm, 380–413 nm, and 658 nm are attributed to the F⁺ center, F center, and the 2nd order peak of the F⁺ center and complex F_n center, respectively. It indicates that the F⁺ center monotonically increases with increasing ion energy. However, it first increases and then decreases with the irradiation dose. The suppression of F center emission with increasing ion energy and dose is discussed. They may indicate that the luminescence is related to the structural damage by swift heavy ions, which is possibly a good parameter for online monitoring of irradiation damage.

快速重离子辐照效应的原位研究：快速重离子对Al2O3的发光

本文报道了氧化铝（Al2O3）单晶在93,245,425和609 MeV Xeq+离子辐照下的原位发光研究结果。在室温下测量了200-800 nm波长范围内的光谱。Al2O3中发光的电子停止功率（Se）的阈值估计约为18.3 keV/nm。在光谱中，336 nm、380 ~ 413 nm和658 nm的观测波段分别归属于F+中心、F中心和F+中心的二阶峰和复Fn中心。结果表明，随着离子能量的增加，F+中心单调增大。但随着辐照剂量的增加，它先增大后减小。讨论了增加离子能量和剂量对F中心发射的抑制作用。这可能表明发光与快速重离子对结构的损伤有关，这可能是在线监测辐照损伤的一个很好的参数。

期刊介绍： Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
