A comprehensive analysis: The effects of 100 MeV Ni7+ ion irradiations on the structural integrity of MoO3 thin films
An effort has been made to comprehensively study the structural modification of the molybdenum trioxide (MoO3) thin film with 100 MeV, Ni7+. The MoO3 nanoparticles were synthesized by hydrothermal method and thin film of MoO3 was fabricated by spin coating technique. MoO3 thin film was subjected to irradiation with 100 MeV, Ni7+ beam with various fluences of 5 × 1012, 1 × 1013, and 3 × 1013 ions cm−2. The structural changes induced by ion beam irradiation were characterized using XRD diffraction, Raman, Fourier Transforms Infrared Spectroscopy (FTIR) UV–visible spectroscopy, and Atomic Force Microscopy (AFM). The synthesized thin film showed an orthorhombic phase and the average crystallite size was 63.8 nm of the pristine sample. it is observed that the crystallinity decreases after irradiation. The Raman study confirmed the XRD findings and also showed that after exposure, intensity of the Raman peaks decreased and the width of the spectra expanded due to a decrement in the crystallinity. The bandgap of the thin films decreased after irradiation as the ion fluence increased up to 3 × 1013 ions cm−2. The findings showed that the ion beam irradiation was directly accountable for the amorphization and lattice defect development in the MoO3 thin films.
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.
