In this study, we investigate the codoping of Bi<sup>3+</sup> and Er<sup>3+</sup> into LiTaO<sub>3</sub> to enhance afterglow performance. Through high-temperature solid-state synthesis, a series of LiTaO<sub>3</sub>:x%Bi<sup>3+</sup>, y%Er<sup>3+</sup> (x = 0 or 0.5%, y = 0.1–4.0%) samples were prepared successfully. Structural characterization confirmed the successful incorporation of Bi<sup>3+</sup> and Er<sup>3+</sup> into the Li⁺ sites without disrupting the host lattice. Photoluminescence studies revealed that Bi³⁺ codoping significantly enhances the green emission of Er³⁺, with optimal performance achieved at 1.0% Er<sup>3+</sup> doping. Thermoluminescence (TL) analysis demonstrated the presence of traps with the depth of 0.748 eV, enabling prolonged afterglow emission at room temperature. The afterglow mechanism involves charge carrier storage in traps under UV excitation, followed by thermal release and recombination at luminescent centers, facilitated by energy transfer from Bi<sup>3+</sup> to Er<sup>3+</sup>. This work provides a strategy for designing a long afterglow phosphor through controlled codoping, offering insights into trap engineering and energy transfer processes in perovskite-based luminescent materials.</p></div>","PeriodicalId":473,"journal":{"name":"Applied Physics A","volume":"131 6","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
