Herein, for further enhancing the relative sensitivity, a time-resolved FIR-based approach was proposed and successfully implemented employing a home-built time-resolved measurement system. By using the time-resolved FIR of Eu\n                    <jats:sup>3+<\/jats:sup>\n                    to Mn\n                    <jats:sup>4+<\/jats:sup>\n                    in BLN:1% Eu\n                    <jats:sup>3+<\/jats:sup>\n                    , 0.1% Mn\n                    <jats:sup>4+<\/jats:sup>\n                    as the sensing parameter, drastic temperature dependence was obtained, and a maximum relative sensitivity of 7.8% K\n                    <jats:sup>\u20131<\/jats:sup>\n                    was achieved, which is remarkably superior to the FI- and lifetime-based methods with the identical sensing material. Excellent reversibility was also demonstrated by heating-cooling cycle tests. These findings indicate the great potential of the time-resolved FIR-based approach for high-performance optical thermometry.\n                  <\/jats:p>","DOI":"10.1364\/ol.600856","type":"journal-article","created":{"date-parts":[[2026,6,1]],"date-time":"2026-06-01T12:00:08Z","timestamp":1780315208000},"page":"3533","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Easily implementable time-resolved fluorescence intensity ratio approach for highly sensitive optical thermometry"],"prefix":"10.1364","volume":"51","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9434-3965","authenticated-orcid":true,"given":"Shaoshuai","family":"Zhou","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01848hk04","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Wang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01848hk04","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xu","family":"Sang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01848hk04","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,6,18]]},"reference":[{"key":"ol-51-13-3533-R1","doi-asserted-by":"publisher","first-page":"e20233","DOI":"10.1002\/anie.202520233","type":"journal-article","volume":"65","author":"Zhao","year":"2025","journal-title":"Angew.
