Such peculiar behavior is uncovered to be associated withnthe thermal excitation of a low-frequency phonon bath, and a theoreticalnmodel involving the excitation-wavelength-dependent populations ofnvibronic levels and the temperature-dependent nonradiative recombinationnprocesses is successfully constructed. Two main governing parameters,nnamely, the thermal activation energy <i>E</i><sub><i>a</i></sub> and the involved average phonon energy Δ<i>E</i>, are thus determined for the distinct thermal behaviorsnof Mn<sup>4+</sup>-ion luminescence. This demonstration may pave thenway for manipulating the thermal behaviors of vibronic luminescencenin solids to some extent.","PeriodicalId":521995,"journal":{"name":"Figshare","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147889422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
