摘要

用12.5、18和23 MeV的碘束辐照氧化石墨烯薄膜。同时，通过原位飞行时间弹性后坐力检测分析监测了化学计量学的变化。辐照膜的最终状态表明它们的还原类似于经过经典热退火程序的样品的还原。核能损失被认为是驱动还原过程的主要力量，尽管电子能量损失似乎在辐照下氢的行为中起重要作用。

In situ elastic recoil detection for graphene oxide analysis

Thin graphene oxide films were irradiated with 12.5, 18 and 23 MeV iodine beams. At the same time, stoichiometry changes have been monitored by the in situ time-of-flight elastic recoil detection analysis. Final state of the irradiated films indicated their reduction is similar to the reduction of samples undergoing classical thermal annealing procedure. Nuclear energy loss was identified as the main force driving reduction process, although electronic energy loss seems to play an important role in behaviour of the hydrogen under irradiation.

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.
