The most common is TL, in which crystal fracture generates opposing charges that excite surrounding molecules. In PL, applied pressure induces light emission via charge recombination. SL occurs in gas-saturated liquids under sudden pressure changes. TIEL has gained increasing attention as it operates without the need for asymmetric crystal structures or strain fields. However, conventional ML faces practical limitations due to its dependence on complex structures or strain fields. In contrast, contact-electro-luminescence (CEL) has emerged as a promising alternative, enabling luminol luminescence via charge transfer and reactive oxygen species generation through contact electrification (CE) between inert dielectrics and water. CEL provides a simpler and more versatile approach than traditional ML techniques, underscoring the pivotal role of charge-transfer processes. This perspective highlights the potential of CEL in expanding ML applications across sensing, energy conversion, and environmental monitoring.<\/jats:p>","DOI":"10.3390\/nano15090656","type":"journal-article","created":{"date-parts":[[2025,5,2]],"date-time":"2025-05-02T11:35:13Z","timestamp":1746185713000},"page":"656","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Revealing the Role of Interfacial Charge Transfer in Mechanoluminescence"],"prefix":"10.3390","volume":"15","author":[{"given":"Xinyi","family":"Huo","sequence":"first","affiliation":[{"name":"School of Science, China University of Geosciences, Beijing 100083, China"},{"name":"Beijing Institute of Nanoenergy and Nanosystems, Chinese Academy of Sciences, Beijing 101400, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shaoxin","family":"Li","sequence":"additional","affiliation":[{"name":"Beijing Institute of Nanoenergy and Nanosystems, Chinese Academy of Sciences, Beijing 101400, China"},{"name":"School of Nanoscience and Engineering, University of Chinese Academy of Sciences, Beijing 100049, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5917-3094","authenticated-orcid":false,"given":"Bing","family":"Sun","sequence":"additional","affiliation":[{"name":"School of Science, China University of Geosciences, Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5530-0380","authenticated-orcid":false,"given":"Zhonglin","family":"Wang","sequence":"additional","affiliation":[{"name":"Beijing Institute of Nanoenergy and Nanosystems, Chinese Academy of Sciences, Beijing 101400, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2670-6362","authenticated-orcid":false,"given":"Di","family":"Wei","sequence":"additional","affiliation":[{"name":"Beijing Institute of Nanoenergy and Nanosystems, Chinese Academy of Sciences, Beijing 101400, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"39","DOI":"10.20517\/ss.2023.33","article-title":"Soft devices empowered by mechanoluminescent materials","volume":"3","author":"Wang","year":"2023","journal-title":"Soft Sci."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2304140","DOI":"10.1002\/adma.202304140","article-title":"Mechanoluminescence and Photoluminescence Heterojunction for Superior Multimode Sensing Platform of Friction, Force, Pressure, and Temperature in Fibers and 3D-Printed Polymers","volume":"35","author":"Zheng","year":"2023","journal-title":"Adv.
