PL spectra of the Ag-containing glass show two broad weakly resolved emission bands in the violet-green spectral range attributed to Ag+ ions and nonplasmonic Ag nanoclusters. Decay kinetics of these bands are nonmonoexponential, characterised by an average lifetime in the microsecond range. A significant enhancement of the PL intensity and PL QY of Tb3+ ions was observed in Tb-Ag codoped LTB glass in comparison with Tb-doped LTB glass.

The structure and optical properties of the samples were systematically studied by the characterizations of x-ray diffraction (XRD), scanning electron microscope (SEM), UV-Vis spectra, photoluminescence (PL) spectra, photoluminescence excitation (PLE) spectra, and quantum efficiency (QE). It was found that the addition of La3+ ions plays significant roles on the luminous performance of phosphors as compared with the nonluminous BaSrCaWO6:Mn (BSCW:Mn), which can be attributed to the Mn2+ → Mn4+ oxidation process induced by La3+ doping. The BSCW:0.5%Mn, 15%La3+ phosphor exhibited a strong emission peak at 685 nm with a CIE chromaticity coordinate at (0.720, 0.279), which is suitable for application in indoor plant cultivations. The BSCW:0.5%Mn, 15%La3+ phosphor exhibited an IQE of 47.8% and a high absorption efficiency of 72.8% with the EQE of 34.8%. Besides, the phosphor also showed the thermal stability with the emission intensity at 423 K being 48% of the emission intensity at 298 K. These results indicate that the synthesized BSCW:0.5%Mn, 15%La3+ phosphor could be a potential phosphor to be applied in plant growth LEDs.","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"40 1","pages":"e70081"},"PeriodicalIF":3.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142980633","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}

Nevertheless, the thermal stability of Mn4+-activated fluoride luminescent materials is still a crucial issue. Herein, a new red Rb2NaVF6:Mn4+ luminescent material with outstanding thermal stability was successfully synthesized through the facial coprecipitation method. Mn4+ ions prefer to occupy VF6 octahedra based on the accurate Rietveld refinement results. Accordingly, the as-prepared Rb2NaVF6:Mn4+ exhibits a broad absorption region from 300 to 500 nm with a maximum of 468 nm, matching well with the near-ultraviolet and blue InGaN chip. Upon 468 nm excitation, Rb2NaVF6:Mn4+ can emit narrow-band red light at 632 nm. Notably, Rb2NaVF6:Mn4+ shows superior antithermal quenching properties, of which the integrated intensities at 175°C can realize as high as 140% than that at 25°C. Owing to the diverse thermal quenching behavior between anti-Stokes and Stokes emission, Rb2NaVF6:Mn4+ displays promising candidates in optical thermometry sensors with a relative sensitivity Sr of 0.49%. This study offers new insight into developing antithermal quenching red Mn4+-activated fluoride luminescent materials.","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"40 1","pages":"e70084"},"PeriodicalIF":3.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142967352","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}

However, most current techniques for ASA analysis have faced challenges like complexity, delayed response times, low throughput, time-consuming procedures, and requirements for expensive equipment and hazardous chemicals for analyte modification. The study is aimed at producing natural carbon quantum dots (NACQDs) from pumpkin seed peels (PSPs), a natural waste material, using a rapid microwave-assisted method. A variety of techniques, including transmission electron microscopy, scanning electron microscopy, energy-dispersive x-ray spectroscopy, and Fourier-transform infrared spectroscopy, were employed to characterize the PSP-based NACQDs. The NACQDs were used as probes for FL analysis of ASA, where the addition of ASA caused fluorescence quenching of the NACQDs. The developed method demonstrated good linearity (r = 0.996), sensitivity, accuracy (percentage recovery ranging from 99.36% to 100.35%), and precision (%RSD less than 0.21%) in the quantification of ASA in the range of 0.3-15 μg/mL. The method's LOD and LOQ values were 0.1 and 0.3 μg/mL, respectively. The successful analysis of ASA in tablet formulations demonstrated the practicality of the proposed method. Greenness assessment tools highlighted its superior eco-friendliness compared to reference techniques.","PeriodicalId":49902,"journal":{"name":"Luminescence","volume":"40 1","pages":"e70072"},"PeriodicalIF":3.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142923624","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}

Various characterization techniques were employed to confirm the optical properties, crystal lattices, and morphology of ZnO NPs. TEM images showed that the ZnO NPs had a spherical shape, with an average size of 40 to 80 nm. The photocatalytic analysis revealed that the synthesized ZnO NPs exhibited substantial activity under visible light, effectively degrading 90.6% of CV in an aqueous solution. The antibacterial activity of synthesized ZnO NPs was evaluated against clinically relevant bacterial strains such as Pseudomonas aeruginosa and Bacillus subtilis, revealing notable zones of inhibition. Moreover, the ZnO NPs exhibited antibiofilm activity of 96.8 ± 0.5% and 98.3 ± 0.3% against P. aeruginosa and Staphylococcus aureus, respectively.

The proposed approach measured the quenching effect of CFP on the fluorescence intensity of NFX in acetate buffer solution. The obtained results show that CFP strongly quenches the fluorescence of NFX in a static mechanism. Under the optimal conditions, plotting the fluorescence quenching values (∆F) against CFP concentrations resulted in two ranges varying from 0.8 to 28 μg/mL (r2 = 0.9979) and from 40 to 92 μg/mL (r2 = 0.9929). Furthermore, the limits of quantification and detection were 2.0526 and 0.6773 μg/mL, respectively. In terms of intra- and inter-day recorded precisions (n = 5), the % RSD ranged between 0.31% and 0.6% and 0.55% and 1.02%, respectively. Additionally, practicality/applicability and the green feature of the new method were considered by BAGI and AGREE automated approaches. The new spectrofluorometric approach was positively applied for the quantification of CFP in injection powder and spiked biological fluids, including spiked human urine and plasma samples.
