The present study introduces a new mercury\u2010free Dielectric Barrier Discharge (DBD) flat lamp, where the biocide action comes from the UV emission produced by rare\u2010earth phosphor obtained by spray pyrolysis, following plasma excitation. In this study, the emission intensity of the prototype lamp is tuned by controlling gas pressure and electrical power, 500\u00a0mbar and 15\u00a0W, corresponding to optimal conditions. In order to characterize the prototype lamp, the energetic output, temperature increase following lamp ignition and ozone production of the source were measured. The bactericidal experiments carried out showed excellent results for several gram\u2010positive and gram\u2010negative bacterial strains, thus demonstrating the high decontamination efficiency of the DBD flat lamp. Finally, the study of the external morphology of the microorganisms after the exposure to the UV emission suggested that other mechanisms than the bacterial DNA damage could be involved in the inactivation process.<\/jats:p>","DOI":"10.1111\/php.12426","type":"journal-article","created":{"date-parts":[[2015,1,28]],"date-time":"2015-01-28T05:24:52Z","timestamp":1422422692000},"page":"526-532","source":"Crossref","is-referenced-by-count":13,"title":["Decontamination Efficiency of a DBD Lamp Containing an UV\u2013C Emitting Phosphor"],"prefix":"10.1111","volume":"91","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2363-0406","authenticated-orcid":false,"given":"Bruno","family":"Caillier","sequence":"first","affiliation":[{"name":"Centre Universitaire Jean Fran\u00e7ois Champollion Diagnostic des Plasmas Hors \u00c9quilibre Universit\u00e9 de Toulouse Albi Cedex 9 France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 Maur\u00edcio Almeida","family":"Caiut","sequence":"additional","affiliation":[{"name":"Department of Chemistry \u2013 FFCLRP University of S\u00e3o Paulo Ribeir\u00e3o Preto SP Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristina","family":"Muja","sequence":"additional","affiliation":[{"name":"Centre Universitaire Jean Fran\u00e7ois Champollion Diagnostic des Plasmas Hors \u00c9quilibre Universit\u00e9 de Toulouse Albi Cedex 9 France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julien","family":"Demoucron","sequence":"additional","affiliation":[{"name":"Centre Universitaire Jean Fran\u00e7ois Champollion Diagnostic des Plasmas Hors \u00c9quilibre Universit\u00e9 de Toulouse Albi Cedex 9 France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert","family":"Mauricot","sequence":"additional","affiliation":[{"name":"Centre d'\u00c9laboration de Mat\u00e9riaux et d'\u00c9tudes Structurales CEMES\/CNRS\u2010BP 94347 Universit\u00e9 de Toulouse Toulouse Cedex 4 France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeanette","family":"Dexpert\u2010Ghys","sequence":"additional","affiliation":[{"name":"Centre d'\u00c9laboration de Mat\u00e9riaux et d'\u00c9tudes Structurales CEMES\/CNRS\u2010BP 94347 Universit\u00e9 de Toulouse Toulouse Cedex 4 France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philippe","family":"Guillot","sequence":"additional","affiliation":[{"name":"Centre Universitaire Jean Fran\u00e7ois Champollion Diagnostic des Plasmas Hors \u00c9quilibre Universit\u00e9 de Toulouse Albi Cedex 9 France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2015,2,22]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-01999-9"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11947-013-1168-7"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2672.2005.02641.x"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jfoodeng.2012.08.022"},{"key":"e_1_2_5_6_1","doi-asserted-by":"crossref","first-page":"1312","DOI":"10.1128\/AEM.65.3.1312-1315.1999","article-title":"Pulsed\u2010light inactivation of food\u2010related microorganisms","volume":"65","author":"Rowan N.
