The Li3PO4 film was deposited on Al2O3 substrate by resistance heating evaporation. Two Au films with designed patterns were formed on the Li3PO4 film by micro-fabrication technologies. The sensing electrode covers one electrode partly using thick-film technology. The electromotive force values between the sensing electrode and the reference electrode were measured and various characteristics were studied including sensitivity, response characteristics, and stability and selectivity. According to the results, we conclude that an optimal working temperature of the SO2 sensor is 500\u2009\u00b0C, the measurement range is 0-100 ppm, the sensitivity is about 32.47 mV\/dec, the response and the recovery time is about 5 min and 10 min, respectively. And the stability and the selectivity of the sensor are good, making it have potential in SO2 measurement of living environment.<\/jats:p>","DOI":"10.1063\/1.4927173","type":"journal-article","created":{"date-parts":[[2015,7,28]],"date-time":"2015-07-28T00:30:29Z","timestamp":1438043429000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":17,"title":["A new potentiometric SO2 sensor based on Li3PO4 electrolyte film and its response characteristics"],"prefix":"10.1063","volume":"86","author":[{"given":"H.","family":"Wang","sequence":"first","affiliation":[{"name":"Xi\u2019an Jiaotong University 1 School of Mechanical Engineering, , Xi\u2019an 710049, China"},{"name":"State Key Laboratory for Manufacturing Systems Engineering 2 , No. 99 Yan Cheung Road, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Z.","family":"Liu","sequence":"additional","affiliation":[{"name":"Xi\u2019an Jiaotong University 1 School of Mechanical Engineering, , Xi\u2019an 710049, China"},{"name":"State Key Laboratory for Manufacturing Systems Engineering 2 , No. 99 Yan Cheung Road, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.","family":"Chen","sequence":"additional","affiliation":[{"name":"Xi\u2019an Jiaotong University 1 School of Mechanical Engineering, , Xi\u2019an 710049, China"},{"name":"State Key Laboratory for Manufacturing Systems Engineering 2 , No. 99 Yan Cheung Road, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Z.","family":"Jiang","sequence":"additional","affiliation":[{"name":"Xi\u2019an Jiaotong University 1 School of Mechanical Engineering, , Xi\u2019an 710049, China"},{"name":"State Key Laboratory for Manufacturing Systems Engineering 2 , No. 99 Yan Cheung Road, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"317","published-online":{"date-parts":[[2015,7,27]]},"reference":[{"key":"2023072804462949300_c1","doi-asserted-by":"publisher","first-page":"2","DOI":"10.1016\/j.snb.2004.12.075","article-title":"Toward innovations of gas sensor technology","volume":"108","year":"2005","journal-title":"Sens.
