“…It shows a set of narrow, well-defined bands in the UV region, which correspond to the f–f electronic transitions in Eu 3+ ions. The most intense band corresponds to the 7 F 0 → 5 L 6 transition and it is located at 394 nm, in good agreement with the literature on Eu 3+ -doped fluorides [12,27]. Figure 6b shows the emission spectra of the Eu 3+ -doped nanoparticles while exciting the samples at 394 nm.…”

Due to the high atomic number of lutetium and the low phonon energy of the fluoride matrix, Lu-based fluoride nanoparticles doped with active lanthanide ions are potential candidates as bioprobes in both X-ray computed tomography and luminescent imaging. This paper shows a method for the fabrication of uniform, water-dispersible Eu3+:(H3O)Lu3F10 nanoparticles doped with different Eu contents. Their luminescent properties were studied by means of excitation and emission spectra as well as decay curves. The X-ray attenuation capacity of the phosphor showing the highest emission intensity was subsequently analyzed and compared with a commercial contrast agent. The results indicated that the 10% Eu3+-doped (H3O)Lu3F10 nanoparticles fabricated with the proposed polyol-based method are good candidates to be used as dual probes for luminescent imaging and X-ray computed tomography.

“…Even without additional water, BmimPF 6 can hydrolyze with the aid of the trace water and hydration water molecules from yttrium chloride hexahydrate [45,48]. During the treatment procedure, PF 6 − can slowly hydrolyze and then produce F − through slowly increasing the temperature [45], as revealed in Equation (1):PF 6 − (IL) + H 2 O → PF 5 ·H 2 O + F − Therefore, this procedure was defined as a fluoride slow-release strategy, which involved fluoride releasing from BmimPF 6 with the assistance of polyol [49].…”

There are only a few inorganic compounds that have evoked as much interest as sodium yttrium fluoride (NaYF4). Its extensive applications in various fields, including transparent displays, luminescence coding, data storage, as well as biological imaging, demand the precise tuning of the crystal phase. Controlling the emergence of the desired α-phase has so far remained a formidable challenge, especially via a simple procedure. Herein, we represented a polyol-assisted fluoride ions slow-release strategy for the rational control of pure cubic phase NaYF4 mesocrystals. The combination of fluorine-containing ionic liquid as a fluoride source and the existence of a polyalcohol as the reactive medium ensure the formation of uniform α-phase mesocrystallines in spite of a higher temperature and/or higher doping level.
