Using single-particle intensity\u2013lifetime analysis, blinking statistics, and photon correlations, we demonstrate that replacing oleic acid (OA) with 3-mercaptopropionic acid (MPA) alters the dominant blinking mechanism in single InP\/ZnS QDs. OA-capped QDs exhibit separated lifetime\u2013intensity clusters that are characteristic of charging-induced Auger blinking. After MPA exchange, the lifetime\u2013intensity relationship becomes continuous and approximately linear. Long-lived bright periods also become less probable, consistent with a shift toward trap-assisted band-edge-carrier blinking. Concurrently, MPA exchange shortens exciton and biexciton lifetimes while increasing the normalized zero-delay coincidence probability, indicating different responses of the single-exciton and biexciton relaxation channels. These concurrent yet distinct changes demonstrate that ligand exchange does not simply alter the average emission intensity but rebalances the competing radiative, Auger-mediated, and trap-assisted relaxation pathways at the single-QD level.<\/jats:p>","DOI":"10.1021\/acs.jpclett.6c02732","type":"journal-article","created":{"date-parts":[[2026,10,5]],"date-time":"2026-10-05T18:01:12Z","timestamp":1791223272000},"page":"11878-11884","source":"Crossref","is-referenced-by-count":0,"title":["Ligand Exchange Reprograms Blinking Dynamics and Photon\nStatistics in Single InP\/ZnS Quantum Dots"],"prefix":"10.1021","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5817-6792","authenticated-orcid":true,"given":"Bin","family":"Li","sequence":"first","affiliation":[{"name":"Shanxi Normal University , , ,","place":["Taiyuan, China, 030031"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guofa","family":"Qu","sequence":"additional","affiliation":[{"name":"Shanxi Normal University , , ,","place":["Taiyuan, China, 030031"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoyao","family":"Ye","sequence":"additional","affiliation":[{"name":"Shanxi Normal University , , ,","place":["Taiyuan, China, 030031"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9273-0451","authenticated-orcid":true,"given":"Ruixiang","family":"Wu","sequence":"additional","affiliation":[{"name":"Shanxi Normal University , , ,","place":["Taiyuan, China, 030031"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shengzhi","family":"Wang","sequence":"additional","affiliation":[{"name":"Shanxi Normal University , , ,","place":["Taiyuan, China, 030031"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9030-0431","authenticated-orcid":true,"given":"Guofeng","family":"Zhang","sequence":"additional","affiliation":[{"name":"Shanxi University , , ,","place":["Taiyuan, China, 030006"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiangyang","family":"Miao","sequence":"additional","affiliation":[{"name":"Shanxi Normal University , , ,","place":["Taiyuan, China, 030031"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,10,5]]},"reference":[{"key":"2026101508210937200_cit1","doi-asserted-by":"publisher","first-page":"640","DOI":"10.1126\/science.aaz8541","article-title":"Semiconductor quantum dots: Technological\nprogress and future challenges","volume":"373","author":"Garci\u0301a de Arquer","year":"2021","journal-title":"Science"},{"key":"2026101508210937200_cit2","doi-asserted-by":"publisher","first-page":"6104","DOI":"10.1021\/acs.nanolett.7b02634","article-title":"Nearly blinking-free,\nhigh-purity single-photon emission\nby colloidal InP\/ZnSe quantum dots","volume":"17","author":"Chandrasekaran","year":"2017","journal-title":"Nano Lett."},{"key":"2026101508210937200_cit3","doi-asserted-by":"publisher","first-page":"742","DOI":"10.1038\/s41578-023-00596-4","article-title":"InP colloidal quantum dots for visible\nand near-infrared\nphotonics","volume":"8","author":"Almeida","year":"2023","journal-title":"Nat.
