Among these, the Mg-doped ZnO system is of particular interest as it offers the opportunity to tune the UV emission by engineering its bandgap via doping control. However, both the doped system and its pristine congener, ZnO, suffer from being highly prone to parasitic defect level emissions, compromising their efficiency as light emitters in the ultraviolet region. Here, employing the process of femtosecond pulsed laser ablation in a liquid (fs-PLAL), we demonstrate the systematic control of enhanced UV-only emission in Mg-doped ZnO nanoparticles using both photoluminescence and cathodoluminescence spectroscopies. The ratio of luminescence intensities corresponding to near band edge emission to defect level emission was found to be six-times higher in Mg-doped ZnO nanoparticles as compared to pristine ZnO. Insights from UV-visible absorption and Raman analysis also reaffirm this defect suppression. This work provides a simple and effective single-step methodology to achieve UV-emission and mitigation of defect emissions in the Mg-doped ZnO system. This is a significant step forward in its deployment for UV emitting optoelectronic devices.<\/jats:p>","DOI":"10.3390\/nano10071326","type":"journal-article","created":{"date-parts":[[2020,7,6]],"date-time":"2020-07-06T11:07:42Z","timestamp":1594033662000},"page":"1326","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Femtosecond Pulse Ablation Assisted Mg-ZnO Nanoparticles for UV-Only Emission"],"prefix":"10.3390","volume":"10","author":[{"given":"Anubhab","family":"Sahoo","sequence":"first","affiliation":[{"name":"Department of Physics, Indian Institute of Technology Madras, Chennai 600036, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muralidhar","family":"Miryala","sequence":"additional","affiliation":[{"name":"Superconducting Material Laboratory, Graduate School of Science and Engineering, Shibaura Institute of Technology, 3-7-5 Toyosu, Koto-Ku, Tokyo 135-8546, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tejendra","family":"Dixit","sequence":"additional","affiliation":[{"name":"Department of Physics, Indian Institute of Technology Madras, Chennai 600036, India"},{"name":"Department of Electronics and Communication Engineering, Indian Institute of Information Technology Design and Manufacturing Kancheepuram, Chennai 600127, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7072-0132","authenticated-orcid":false,"given":"Alicja","family":"Klimkowicz","sequence":"additional","affiliation":[{"name":"Department of Engineering Science and Mechanics, Shibaura Institute of Techno.logy, 3-7-5 Toyosu, Koto-Ku, Tokyo 135-8546, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bellarmine","family":"Francis","sequence":"additional","affiliation":[{"name":"Department of Physics, Indian Institute of Technology Madras, Chennai 600036, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masato","family":"Murakami","sequence":"additional","affiliation":[{"name":"Superconducting Material Laboratory, Graduate School of Science and Engineering, Shibaura Institute of Technology, 3-7-5 Toyosu, Koto-Ku, Tokyo 135-8546, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mamidanna Sri Ramachandra","family":"Rao","sequence":"additional","affiliation":[{"name":"Department of Physics, Indian Institute of Technology Madras, Chennai 600036, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sivarama","family":"Krishnan","sequence":"additional","affiliation":[{"name":"Department of Physics, Indian Institute of Technology Madras, Chennai 600036, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,7,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"433001","DOI":"10.1088\/0022-3727\/49\/43\/433001","article-title":"The 2016 oxide electronic materials and oxide interfaces roadmap","volume":"49","author":"Lorenz","year":"2016","journal-title":"J.
