Gd(III), Er(III)) and

(Eu(dpm)3) induced by microwave heating in the ionic liquids
(ILs) 1-butyl-3-methylimidazolium tetrafluoroborate
([BMIm][BF4]), 1-butyl-3-methylimidazolium
bis(trifluoromethylsulfonyl)imide ([BMIm][NTf2]) and in
propylene carbonate (PC) yield oxide-free rare-earth metal
nanoparticles (RE-NPs) in [BMIm][NTf2] and PC for RE = Pr,
Gd and Er or rare-earth metal-fluoride nanoparticles
(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
diameter of (11 ± 6) to (38 ± 17) nm for the REF3-NPs from
[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).},
