Nonetheless, the poor moisture resistance of these phosphors impedes their commercialization. Herein, we proposed the dual strategies of \u201csolid solution design\u201d and \u201ccharge compensation\u201d to design K2Nb1\u2212xMoxF7 novel fluoride solid solution system, and synthesized the Mn4+-activated K2Nb1\u2212xMoxF7 (0 \u2264 x \u2264 0.15, x represents the mol % of Mo6+ in the initial solution) red phosphors via co-precipitation method. The doping of Mo6+ not only significantly improve the moisture resistance of the K2NbF7: Mn4+ phosphor without any passivation and surface coating, but also effectively enhance the luminescence properties and thermal stability. In particular, the obtained K2Nb1\u2212xMoxF7: Mn4+ (x = 0.05) phosphor possesses the quantum yield of 47.22% and retains 69.95% of its initial emission intensity at 353 K. Notably, the normalized intensity of the red emission peak (627 nm) for the K2Nb1\u2212xMoxF7: Mn4+ (x = 0.05) phosphor is 86.37% of its initial intensity after immersion for 1440 min, prominently higher than that of the K2NbF7: Mn4+ phosphor. Moreover, a high-performance WLED with high CRI of 88 and low CCT of 3979 K is fabricated by combining blue chip (InGaN), yellow phosphor (Y3Al5O12: Ce3+) and the K2Nb1\u2212xMoxF7: Mn4+ (x = 0.05) red phosphor. Our findings convincingly demonstrate that the K2Nb1\u2212xMoxF7: Mn4+ phosphors have a good practical application in WLEDs.<\/jats:p>","DOI":"10.3390\/molecules28114566","type":"journal-article","created":{"date-parts":[[2023,6,6]],"date-time":"2023-06-06T02:08:15Z","timestamp":1686017295000},"page":"4566","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Novel Mn4+-Activated K2Nb1\u2212xMoxF7 (0 \u2264 x \u2264 0.15) Solid Solution Red Phosphors with Superior Moisture Resistance and Good Thermal Stability"],"prefix":"10.3390","volume":"28","author":[{"given":"Yuhan","family":"Gao","sequence":"first","affiliation":[{"name":"College of Chemistry and Materials Science, Sichuan Normal University, Chengdu 610066, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lei","family":"Feng","sequence":"additional","affiliation":[{"name":"College of Chemistry and Materials Science, Sichuan Normal University, Chengdu 610066, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Linglin","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Chemistry and Materials Science, Sichuan Normal University, Chengdu 610066, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun","family":"Zheng","sequence":"additional","affiliation":[{"name":"College of Chemistry and Materials Science, Sichuan Normal University, Chengdu 610066, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feiyao","family":"Ren","sequence":"additional","affiliation":[{"name":"College of Chemistry and Materials Science, Sichuan Normal University, Chengdu 610066, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Siyu","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Chemistry and Materials Science, Sichuan Normal University, Chengdu 610066, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5576-7626","authenticated-orcid":false,"given":"Zhanglei","family":"Ning","sequence":"additional","affiliation":[{"name":"College of Chemistry and Materials Science, Sichuan Normal University, Chengdu 610066, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ting","family":"Zhou","sequence":"additional","affiliation":[{"name":"College of Chemistry and Materials Science, Sichuan Normal University, Chengdu 610066, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaochun","family":"Wu","sequence":"additional","affiliation":[{"name":"College of Chemistry and Materials Science, Sichuan Normal University, Chengdu 610066, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin","family":"Lai","sequence":"additional","affiliation":[{"name":"College of Chemistry and Materials Science, Sichuan Normal University, Chengdu 610066, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3600-9712","authenticated-orcid":false,"given":"Daojiang","family":"Gao","sequence":"additional","affiliation":[{"name":"College of Chemistry and Materials Science, Sichuan Normal University, Chengdu 610066, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"98","DOI":"10.1016\/j.materresbull.2019.03.020","article-title":"Improving the moisture resistance and luminescent properties of K2TiF6: Mn4+ by coating with CaF2","volume":"115","author":"Dong","year":"2019","journal-title":"Mater.
