Abstract:
Through a polyethylene-glycol-assisted hydrothermal method, a series of potassium fluoride (KF)–Yttrium (III) fluoride (YF 3 ) system materials have been synthesized. By controlling the reactant ratios of KF: rare earth ions (RE 3+ ), the hydrothermal temperatures, and the pH values of the prepared solutions, the final products can evolve among the orthorhombic phase of YF 3 and/or the tetragonal phase of potassium triyttrium decafluoride (KY 3 F 10 ) and/or the cubic phase of potassium yttrium tetrafluoride (KYF 4 ). The final products are characterized by the x-ray diffraction (XRD) patterns, the field-emission scanning electron microscopy (FE-SEM) images, the energy-dispersive spectroscopy (EDS) patterns, the photoluminescence (PL) spectra, and the luminescent dynamic decay curves. The XRD patterns of the samples suggest the phase evolution of the final products. The FE-SEM images and the EDS patterns prove that. Europium ion (Eu 3+ ) acting as a probe, its PL spectra and the luminescent decay curves all put together prove the phase evolution of the final products. The research can be extended to study the other KF–REF 3 system materials.
