Their grain sizes, microstrain, morphological features, leakage current characteristics, and photoluminescence (PL) emission behavior are investigated and compared with each other. X\u2010ray diffraction (XRD) technique has been utilized to compute the grain sizes and crystalline strain values for the thin films and nanopowders of BFO through Williamson\u2013Hall (W\u2013H) plots. XRD and Raman peaks of the deposited thin film and synthesized nanopowders of BFO confirm the formation of rhombohedral unit cell character and its vibrational structure. Topographical analysis of nanopowders and thin films of BFO from scanning electron microscopy (SEM) and atomic force microscopy (AFM) measurements reveals the spherical morphology of grown particles. Suppression of emission peaks, as noticed from PL spectra for BFO nanopowders and thin film, indicates the possible electron defect level transitions due to oxygen vacancies. Leakage current density studies suggest the detectable flow of current in both study of specimen.<\/jats:p>","DOI":"10.1002\/crat.202200143","type":"journal-article","created":{"date-parts":[[2023,7,27]],"date-time":"2023-07-27T05:30:23Z","timestamp":1690435823000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A Comparative Analysis on the Crystalline Behavior, Topographical, Photoluminescence, and Leakage Current Characteristics of BiFeO<sub>3<\/sub> Nanopowders and Thin Films"],"prefix":"10.1002","volume":"58","author":[{"given":"Ramasamy","family":"Venkatapathy","sequence":"first","affiliation":[{"name":"Department of Science and Humanities University College of Engineering Arni, Thatchur (Anna University)  Chennai 632 326 India"}]},{"given":"J.","family":"Ramana Ramya","sequence":"additional","affiliation":[{"name":"Department of Periodontics Saveetha Dental College and Hospitals, Saveetha Institute of Medical and Technical Sciences  Chennai 600077 India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7516-7110","authenticated-orcid":false,"given":"V.
