Here we propose a novel white OLED based on ultrathin emissive layers (EMLs). The novel efficient device structure is constructed based on an interface exciplex structure. Color-stable or color-tunable white OLEDs can be realized by tuning the interlayer thickness. The resulting color-tunable white device obtains a maximum power efficiency of 32.03 lm\/W with a correlated color temperature span from 4091 K to 5376 K. Furthermore, the luminescence mechanism is thoroughly investigated. The shift of the spectra in the color-tunable device is mainly attributed to the movement of the main exciton recombination zone.<\/jats:p>","DOI":"10.3390\/mi17080940","type":"journal-article","created":{"date-parts":[[2026,8,7]],"date-time":"2026-08-07T09:14:28Z","timestamp":1786094068000},"page":"940","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Efficient Non-Doped White Organic Light-Emitting Diodes Based on an Interface Exciplex Structure"],"prefix":"10.3390","volume":"17","author":[{"given":"Qing","family":"Zhao","sequence":"first","affiliation":[{"name":"Key Laboratory of Geophysical Exploration Equipment, Ministry of Education, College of Instrumentation and Electrical Engineering, Jilin University, Changchun 130012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ping","family":"Chen","sequence":"additional","affiliation":[{"name":"Institute of Physics and Electronic Information, Yantai University, Yantai 264005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4281-7417","authenticated-orcid":false,"given":"Tianyu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Geophysical Exploration Equipment, Ministry of Education, College of Instrumentation and Electrical Engineering, Jilin University, Changchun 130012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1219","DOI":"10.1021\/am507050g","article-title":"Mixing of phosphorescent and exciplex emission in efficient organic electroluminescent devices","volume":"7","author":"Cherpak","year":"2015","journal-title":"ACS Appl.
