This paper implements modification of tungsten oxide film using ion implantation and a physical characterization of the film. The film was implanted with nitrogen at energies between 10 keV and 40 keV and ion dose range 1014–1016 cm-2. The surface morphology of the film after implantation has been modified as observed using electron microscopy. The transmittance of the film was found to decrease with increasing implantation energy and ion dose as measured using conventional spectrophotometer. Depth profile of nitrogen was analyzed using Secondary Ion Mass Spectroscopy (SIMS) and found a peak of nitrogen across the depth of the implanted layer. The amount of nitrogen was found to increase with increasing ion dose and energy. From electron diffraction a broader diffraction rings were revealed from both the implanted and un-implanted layers, indicating that the crystalline properties of the tungsten oxide film after ion implantation remains the same.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
