When illuminated by light with a photon energy between 3.18 and 5.39 eV, the PL intensity gradually increases over hundreds of seconds before reaching a steady level. This phenomenon is known as photo-charging (PC). The AG decays according to the Becquerel law with a characteristic time of tens of seconds. Subsequent heating of the phosphors results in TL, which peaks at about 70 °C and has an activation energy of about 0.65 eV. Although the intensity of PL, AG and TL are significantly higher for the Eu-doped sample than for the un-doped sample, the values of the parameters that govern the PC, TL and AG are very similar for both samples. In particularly the emission spectra of PL, AG, and TL for both samples are very similar in shape, exhibiting a single emission band that peaks at approximately 2.8 eV with a width of 0.3 eV. This implies that the recombination or luminescence centers are intrinsic defects, presumably oxygen vacancies. The PL excitation spectra for the doped and undoped samples exhibit an excitation region around 3.9 eV and one around 4.9 eV. However, the excitation regions for the Eu-doped sample are broader and exhibit additional features indicating the participation of Eu in the absorption of photon energy. The absence of the Eu emission in the PL emission spectra suggest that the excitation energy is transferred from the Eu to the oxygen vacancy. The AG and TL creation spectra for both samples grow monotonously with increasing excitation photon energy and seem unrelated to the PL excitation spectra. This suggests that the role of Eu in enhancing the AG and TL intensity is mainly to facilitate the formation oxygen vacancies.</div></div>","PeriodicalId":16159,"journal":{"name":"Journal of Luminescence","volume":"286 ","pages":"Article 121407"},"PeriodicalIF":3.3,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144632813","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}

But the unique features of neutrons render accurate dose measurements and monitoring. The exceptional structural stability of hexagonal boron nitride (h-BN) and the presence of boron has made it a viable option for neutron dosimetry. The present work investigates the thermoluminescence (TL) dosimetric characteristics of neutron irradiated h-BN powder, focusing on its dose-response, glow curve features, linearity index, sensitivity, fading and reproducibility properties according to the standard TL procedure. The findings demonstrate that h-BN presents a clearly defined TL glow curve with a peak-maxima around 245 °C, indicating its potential application in neutron dosimetry covering the dose range of 4–15 Gy. This study reveals that h-BN exhibits greater linearity with sublinear behavior. The TL sensitivity remains almost unaffected by increasing neutron doses and the appropriateness for repeated dose measurements is confirmed by reproducibility experiments, which show high reliability with a standard variation of 2.39 %. Furthermore, after 28 days of irradiation, fading analysis shows minimal signal loss (⁓19 %), demonstrating that charge carriers retain in trap for long period. Moreover, the kinetic parameters were determined through the application of initial rise, glow curve deconvolution, and peak shape methods. The observed extended lifetimes indicate that traps can efficiently retain electron-hole pairs for an extended period, a key feature suitable for TL dosimetry. These accumulated results validate h-BN as a highly stable and effective neutron dosimeter, ideally suited for situations that demand precise and consistent dose measurement.</div></div>","PeriodicalId":16159,"journal":{"name":"Journal of Luminescence","volume":"286 ","pages":"Article 121411"},"PeriodicalIF":3.3,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144614675","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}

In this work, we critically examine both this mechanism of luminescence in vanadates and two mechanisms that are often used to explain their luminescent efficiency. By correlating published optical properties (e.g. excitation energies, Stokes shifts, and emission bandwidths) with structural properties (e.g. bond lengths and bond angles) on 77 different vanadate phosphors, we find that there is no strong evidence in favour of the proposed mechanisms used to describe luminescence as well as quenching thereof. Instead, we suggest a mechanism in which the luminescent charge transfer state is not directly formed upon photoexcitation but rather formed after initial electron trapping following bandgap excitation. The resulting luminescent state is, therefore, likely to be more appropriately termed a self-trapped exciton.</div></div>","PeriodicalId":16159,"journal":{"name":"Journal of Luminescence","volume":"286 ","pages":"Article 121397"},"PeriodicalIF":3.3,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144687355","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}

In this study, we address this critical issue through a room-temperature Rb⁺ ion lattice doping strategy, which synergistically optimizes the performance of CsPbBr₃ QDs via defect passivation and carrier dynamics modulation. Our experimental results demonstrate that Rb ⁺ doping not only tailors the bandgap of CsPbBr₃ QDs to the range of 2.40–2.44 eV through band engineering but also significantly enhances the photoluminescence quantum yield from 77.18 % to 90.31 %.

Based on the Rb ⁺ doped CsPbBr₃ QDs, we constructed green perovskite quantum dot light-emitting diodes (PQLEDs) that exhibit breakthrough performance, achieving a maximum luminance of 82,740 cd m⁻², which is among the highest reported values for A-site-doped systems.
