In this regard, co-doping strategies involving Yb3+ have emerged as a promising approach to achieve broader spectral coverage with improved performance. Herein, a series of Li3Cs2Sr2B3P6O24: Cr3+, Yb3+ co-doped phosphors are developed for the first time. Upon 450-nm excitation, the optimal LCSBPO: 0.1Cr3+, 0.02Yb3+ phosphor delivers intense emission covering 900–1150 nm, which originated from the Stark-split 2F5/2 → 2F7/2 transitions of Yb3+. Co-doping results in a remarkable 61-fold increase in Yb3+ emission compared to mono-doped Yb3+ and a three-fold enhancement in overall luminescence relative to LCSBPO: 0.1Cr3+. Specifically, the internal quantum efficiency (IQE) improves from 33.7% to 50.6%. Despite the poor luminous thermal stability at 120°C (39.5%), the distinct thermal responses of Cr3+ and Yb3+ emissions enable ratiometric temperature sensing with a high relative sensitivity (Sr) of 1.93% K−1 at 30°C. Additionally, an NIR pc-LED fabricated by integrating LCSBPO: 0.1Cr3+, 0.02Yb3+ with a 450-nm blue LED demonstrates promising practical applications in night vision imaging and non-destructive analysis.\u0000 </div>","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"40 8","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144832587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, the development of persistent luminescence phosphors capable of excitation under blue light is of critical importance. Bright green light Ca8−xMg3AlGaSi7O28:x%Eu2+ phosphors were synthesized by the high-temperature solid-state reaction method.

Ca2+ is surrounded by 8 O2− ions, forming a Cs point-symmetric CaO8 polyhedron. Ca2+ and Eu2+ share their crystal structure sites and connect eight O2− to form Ca/EuO8.
