Summary: In this work, Eu2+ doped Ba2Ca(BO3)2 phosphors were prepared using the combustion method under different fuel and annealing temperature conditions. XRD, SEM, and PL spectra were used to investigate the optimal conditions for the preparation of Ba2Ca(BO3)2:Eu2+ phosphors. The study found that annealing the Ba2Ca(BO3)2:Eu2+ sample at 700 degrees C in air allowed the formation of Eu3+ state in the Ba2Ca(BO3)2 host lattice, and the phonon sideband spectrum was analyzed to determine the phonon energies. The charge transfer energy obtained from the excitation spectra of Ba2Ca(BO3)2:Eu3+ samples was used to predict the energy levels of lanthanide (Ln) ions. Additionally, the vacuum referred binding energy (VRBE) scheme was constructed for all lanthanides in the Ba2Ca(BO3)2 host lattice and used to discuss the potential of several Ln3+ ions doped Ba2Ca(BO3)2 as thermoluminescence materials.

Summary: Narrow dips were observed in the excitation spectra of alkaline earth fluorides doped with ErF3 or/and YbF3, which are in agreement with the narrow absorption lines of Er3+ and Yb3+ measured previously. The absorption lines of the crystals were calculated from the excitation spectra. These observed dips are due to the absorption lines of 4f-5d transitions in lanthanide ions.

Summary: Developing a new Eu2+-doped blue-green phosphor with tunable spectral in silicate materials is challenging but important for high-quality phosphor-converted white light-emitting diodes. In this study, a series of NaBaScxLu1-xSi2O7: Eu2+ phosphors with blue-green color-tunable luminescence were designed. By modulating the ratio of Sc/Lu, both the photoluminescence and thermal stability properties can be controlled. The introduction of Sc3+ significantly enhances the emission intensity, quantum efficiency, and thermal stability of the phosphors.

Summary: Fluoride based phosphors are valuable in the field of luminescence, especially in display devices and WLED applications. In this study, a series of Sm3+, Eu3+ activated/co-activated Sr6Ca4(PO4)F2 phosphors were prepared using the combustion method and citric acid as a fuel. The crystalline nature of the samples was confirmed through XRD characterization, while the morphological and elemental analyses were conducted using SEM and EDS. The vibrational features of the phosphors were confirmed by FTIR analysis. The photoluminescence properties showed color tunability from orange to red with co-doping of Sm3+ and Eu3+ ions, and the color purity was observed to be 99.15%. These results suggest that the Sm3+, Eu3+ activated/co-activated Sr6Ca4(PO4)6F2 phosphors are potential candidates for WLED and display device applications. (c) 2022 Elsevier B.V.

Summary: This article investigates the impact of monovalent cation doping on the optical properties of rare earth (RE = Eu3+, Tb3+) co-doped Ca14Zn6Al10O35 synthesized through a low temperature combustion method. X-ray diffraction measurement confirms the crystalline phase of the Ca14Zn6Al10O35 phosphor. Under near-ultraviolet light excitation, Eu3+-doped Ca14Zn6Al10O35 displays Eu3+ emission bands with a maximum wavelength of approximately 470 nm, as well as peaks at 593 nm and 615 nm. Tb3+-doped Ca14Zn6Al10O35 exhibits a green emission band centered at 544 nm under near-ultraviolet range. Additionally, the energy transfer process in the Eu3+/Tb3+ pair and the enhancement in photoluminescence (PL) intensity with different charge compensation doping were studied. The obtained optimum PL emission intensity in a broad and intense visible spectral range could be significant for the fabrication of white light emitting diodes (WLEDs).

Summary: In this study, selected elements were incorporated into the anodic titanium oxide in situ during the titanium anodization process to modify its bandgap. The main objective was to achieve photoactivity of the anodic titanium oxide over a wider range of sunlight wavelengths. The successful incorporation of the selected elements into the anodic titanium oxide was confirmed. It was observed that the anodic titanium oxides produced at 60 V had bandgap values in the visible region of sunlight. The smallest bandgap value was obtained for the manganese-modified anodic titanium oxide, with a corresponding wavelength of 486.89 nm and a blue color. Additionally, the pH of the electrolyte was found to significantly influence the thickness of the anodic titanium oxide layer. The formation of barrier oxides with properties similar to coatings made by nitriding processes during the anodization process was reported for the first time.

The peaks observed in the 650-750 nm range are believed to be beneficial for plant growth. Therefore, the suggested glass material shows promise in cultivating far-red emitting plants.

Summary: In this study, Tb3+/Eu3+ activated/co-activated LiAl(PO3)(4) phosphor was prepared by a wet chemical method, and the effect of R+ (Na+, K+) ions on the photoluminescence properties of these phosphors was investigated. The results showed that the charge compensation of Na+ and K+ ions significantly affected the photoluminescence intensity of Tb3+, Eu3+ co-activated LiAl(PO3)(4) phosphors. The photoluminescence intensity of the phosphors was enhanced by factors of 1.2 and 1.4 when Na+ and K+ charge compensators were introduced, respectively. These findings suggest the potential candidacy of the studied phosphor for further improvement in photoluminescence properties for solid-state lighting applications.
