Synthesis and Characterization of Terbium Doped Strontium Aluminate Nanophosphor
Abstract: Luminescence investigations of Tb activated strontium aluminate phosphors prepared using the sol-gel method are described. The phosphor has been characterized by powder X-ray diffraction scanning electron microscope. Optical properties were studied by photoluminescence spectra. Photoluminescence studies of the prepared phosphors showed prominent IR emission, apart from near-band edge emission and green emission. Keywords: SrAl4O7, nanomaterial, sol-gel, photoluminescence, X-ray powder diffraction Cite this Article Jisha VT, Suresh G. Synthesis and Characterization …

Synthesis and Characterization of Strontium Aluminate Nanophosphors
Abstract: Monoclinic SrAl4O7 nanophosphors with different weight percentage of aluminium were synthesized by low temperature sol-gel method. The morphology, composition and structure of the synthesized phosphors were characterized by scanning electron microscope (SEM), energy dispersive X-ray (EDX), photoluminescence emission spectra (PL) and X-ray diffraction (XRD) respectively. It was found that PL emission was obtained at 395, 520, and 790 nm corresponding to blue, green and IR region of the spectrum, respectively. …

Characterization of Mn Dopped SrAlO Nano-Phosphors Prepared via Sol-Gel Method
Abstract: Strontium aluminate with Mn dopped phosphor was synthesized by Sol-Gel method using Strontium Acetate, Aluminium Acetate as raw material and 2-methoxyethanol as complexing agent. The transparent sol was preheated at 100°C for 2 h and then the precursor was finally annealed at 950°C for 2 h. The phosphor emits luminescence with peak wavelength at 395 nm and 520 nm under near-ultraviolet excitation at 360 nm. The morphology, composition and structure …

Synthesis and Photoluminescence Dynamics of Europium (III) and Terbium (III) Co-doped of GdSrAl3O7 Color-Tunable Nanophosphors
Abstract: A series of Europium (III) and Terbium (III) co-doped GdSrAl3O7 color-tunable nanophosphors were synthesized by a simplistic, streamlined and self-propagating, urea-assisted solution combustion synthesis process. The structural and luminescence characteristics of synthesized Eu3+/Tb3+ co-doped Gadolinium Strontium Aluminate nanocrystalline phosphors were validated using powder X- ray diffraction (PXRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X- ray analysis (EDAX), and photoluminescence spectra studies. The morphological studies revealed that …

Kinetics of Crystallization and Microstructural Evolution of Commercial Fluorophlogopite Machinable Glass- Ceramics in the System SrO∙4MgO∙Al2O3∙ 6SiO2∙2MgF2 with Varying in B2O3
Abstract: Glass materials based on fluorophlogopite stoichiometry with varying concentrations of B₂O₃ were synthesized using the melt-casting method, followed by heat treatment at different crystallization temperatures. The resulting glass and glass–ceramic samples were characterized using differential thermal analysis (DTA), scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier-transform infrared (FT-IR) spectroscopy. Kinetic analysis revealed that the activation energies required for the formation of glass–ceramics were 192.77 kJ mol⁻¹ and 210.47 kJ …

Sol–Gel Synthesis of SrAl4O7 and Defect-Related Luminescence Properties
Abstract: Single phase of monoclinic SrAl4O7 is synthesized by sol–gel process at a markedly lower temperature as compared to conventional solid-state reaction. The sol–gel derived samples were characterized by thermal gravimetric analysis (TGA), X-ray powder diffraction (XRD) analysis, scanning electron microscope (SEM) and spectrofluorometer. The XRD analysis shows that the strontium aluminate has the monoclinic (α-SrA2) structure. It was demonstrated that the PL emission was obtained at 395 nm, 510 nm …
