Traditional methods to enhance CRI often come at the expense of thermal stability, posing a challenge for widespread adoption. To address this issue, we proposed a multi-component co-doping strategy by incorporating Lu³⁺ and Mn²⁺/Si⁴⁺ into Ce: YAG PCs. Lu³⁺ incorporation stabilized the crystal lattice, maintained the spatial separation between Ce³⁺ and Mn²⁺, and reduced Ce³⁺-Mn²⁺ energy transfer, thereby suppressing nonradiative transitions and ensuring excellent thermal stability. Additionally, Mn²⁺-Si⁴⁺ co-doping achieved high-concentration incorporation through charge compensation, effectively sustaining strong red emission to enhance the CRI. The optimized Mn10 sample demonstrated exceptional thermal stability, retaining 83.2 % of its emission intensity at 423 K. Moreover, the CRI of Ce,Mn-Si:YLuAG increased from 57.5 to 84.5, a 47 % improvement compared with Ce:YLuAG under high-power LED excitation. These results indicated that Ce, Mn-Si: YLuAG PC, with its excellent CRI and thermal stability, is a highly promising color converter for highpower white LEDs and LDs. <strong>Keywords</strong>: Ce: YAG phosphor ceramic; Ce³⁺-Mn²⁺ codoping; white LDs; color rendering index; crystal-field splitting.</div></div>","PeriodicalId":16159,"journal":{"name":"Journal of Luminescence","volume":"286 ","pages":"Article 121386"},"PeriodicalIF":3.3,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144548660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Structural, vibrational, and morphological analyses were performed using XRD with Rietveld refinement, Raman and FTIR spectroscopy, and SEM–EDS. These analyses confirmed the successful incorporation of dopants without compromising the borate lattice. Photoluminescence (PL) measurements under near-UV excitation (377 nm) showed intense green emission attributed to the ⁵D₄ → ⁷F₅ transition of Tb³⁺, with Li⁺ co-doping producing the greatest enhancement (∼2.7 × ) in emission intensity. Lifetime measurements revealed longer decay times with co-doping, suggesting reduced non-radiative relaxation processes. Judd–Ofelt (J–O) analysis confirmed strong radiative transitions and high internal quantum efficiency (η ≈ 48.4 %). The internal quantum efficiency (IQE) of 48.4 % was estimated using Judd–Ofelt theory, which is based on radiative transition probabilities derived from emission spectra. This method, while theoretical, is widely accepted for powdered phosphors and provides insight into the intrinsic radiative efficiency of the activator ions. Although absolute quantum yield (QY) measurements are typically obtained using integrating sphere systems to account for all optical losses, in this study, such measurements were not performed. Nonetheless, the strong agreement between radiative parameters and observed photoluminescence behavior supports the reliability of the calculated efficiency. In this study, J–O parameters were derived from the integrated emission spectra of Tb³⁺ transitions, following an emission-based approach that has been increasingly employed for powdered phosphors due to its experimental feasibility. Colorimetric analysis using CIE chromaticity diagrams validated the tunable green emission behaviour of the phosphors. Minor deviations from ideal green were linked to background blue emission from the host matrix, a feature that may offer spectral advantages in multifunctional optical applications. Furthermore, the phosphor exhibited a rare negative thermal quenching (NTQ) behavior, maintaining or enhancing emission intensity up to 550 K, which is superior to many commercial green phosphors.These results highlight the crucial role of alkali ion co-doping in tuning the local crystal field, enhancing emission efficiency, and paving the way for the development of efficient green-emitting phosphors for solid-state lighting applications.</div></div>","PeriodicalId":16159,"journal":{"name":"Journal of Luminescence","volume":"286 ","pages":"Article 121380"},"PeriodicalIF":3.3,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144470627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
