Doping is an efficient way to enhance the humidity response of TiO2. Eu-doped TiO2 material was investigated in both theoretical simulations and experiments. In a simulation based on density functional theory, a doped Eu atom can increase the performance of humidity sensors by producing more oxygen vacancies than undoped TiO2. In these experiments, Eu-doped TiO2 nanorods were prepared by hydrothermal synthesis, and the results also confirm the theoretical prediction. When the doping mole ratio is 5 mol%, the response of the humidity sensor reaches 23,997.0, the wet hysteresis is 2.3% and the response\/recovery time is 3\/13.1 s. This study not only improves the basis for preparation of high-performance TiO2 humidity sensors, but also fills the research gap on rare earth Eu-doped TiO2 as a humidity-sensitive material.<\/jats:p>","DOI":"10.3390\/s24134142","type":"journal-article","created":{"date-parts":[[2024,6,26]],"date-time":"2024-06-26T09:29:33Z","timestamp":1719394173000},"page":"4142","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Preparation and Mechanism Analysis of High-Performance Humidity Sensor Based on Eu-Doped TiO2"],"prefix":"10.3390","volume":"24","author":[{"given":"Ling","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Physical Science and Technology, Xinjiang University, Urumqi 830017, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chu","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Physical Science and Technology, Xinjiang University, Urumqi 830017, China"},{"name":"Xinjiang Key Laboratory of Solid State Physics and Devices, Xinjiang University, Urumqi 830017, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0221-016X","authenticated-orcid":false,"given":"Hongyan","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Physical Science and Technology, Xinjiang University, Urumqi 830017, China"},{"name":"Xinjiang Key Laboratory of Solid State Physics and Devices, Xinjiang University, Urumqi 830017, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3170","DOI":"10.1002\/adma.201500940","article-title":"Self-Assembly of an Amphiphilic \u03c0-Conjugated Dyad into Fibers: Ultrafast and Ultrasensitive Humidity Sensor","volume":"27","author":"Squillaci","year":"2015","journal-title":"Adv.
