                      (REF3-NPs) in the fluoride-donating IL [BMIm][BF4] for RE =
                      Pr, Eu, Gd and Er. The crystalline phases and the absence of
                      significant oxide impurities in RE-NPs and REF3-NPs were
                      verified by powder X-ray diffraction (PXRD), selected area
                      electron diffraction (SAED) and high-resolution X-ray
                      photoelectron spectroscopy (XPS). The size distributions of
                      the nanoparticles were determined by transmission electron
                      microscopy (TEM) and high-angle annular dark-field scanning
                      transmission electron microscopy (HAADF-STEM) to an average

                      [BMIm][BF4]. The RE-NPs from [BMIm][NTf2] or PC showed
                      diameters of (1.5 ± 0.5) to (5 ± 1) nm. The
                      characterization was completed by energy-dispersive X-ray
                      spectroscopy (EDX).},
