Repair effect of He+ ions in borosilicate glass by sequential irradiation
The structural variations from alpha decay in borosilicate glasses attract much attention. The glass samples were irradiated with single and sequential beams in Xe20+ and He+ ions. Sequential irradiation means the glasses, which were pre-irradiated with Xe20+ ions, were irradiated with He+ions. The variations in macroscopic properties and microstructure were analyzed by nanoindentation, Raman spectra, infrared spectra and XPS spectra, respectively. After He+ ion irradiation, the hardness of glasses decreases, and the BO4 units increase in the glasses, attributed to the migration of Na on the sample surface. The hardness recovery was observed in sequential irradiation. Combined with the results of single ion irradiation, a reason for hardness recovery is that the migration of Na in deep layer causes the BO3 structure to transform into BO4 structure after He+ions irradiation. The variation of boron structures in sequential irradiation could be considered as the superposition of two single irradiation effects.
期刊介绍：
The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid.
In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
