“…This emission is centred around 300 nm in the crystals and a band related to some perturbed states (which lie in the vicinity of the surface) can be detected between 300 and 350 nm. 27 A comparable spectrum is obtained for the CeF 3 NPs reported here, though the weak emission due to perturbed states is slightly shifted towards longer wavelength under X-ray excitation and appears as a bump in the region 360-425 nm.…”

A series of anhydrous cerium(III) trifluoroacetate complexes with neutral O-donor ligands, namely Ce2(OAc)(TFA)5(DMF)3 (1), Ce(TFA)3(L)x [x = 2, L = THF (2), DMF (3), DMSO (4); x = 1, L = diglyme (5)] and Ce2(TFA)6(DMSO)x(DMF)y [x = 6, y = 0 (6); x = 4, y = 2 (7)] (where OAc = acetate, TFA = trifluoroacetate, THF = tetrahydrofuran, DMF = dimethylformamide, DMSO = dimethylsulphoxide, and diglyme = MeO(C2H4O)2Me] were synthesized and completely characterized by elemental analysis, FT-IR spectroscopy and TG-DTA-MS studies. A partially hydrated complex [Ce(TFA)3(diglyme)(H2O)] (8) was obtained by slow evaporation of the THF solution of anhydrous 5 in the air. The single crystal X-ray diffraction analysis of 1, 3, 4, and 6–8 showed the versatile bonding mode of the TFA ligand (terminal, chelating and bridging). These complexes, on decomposition in 1-octadecene in inert atmosphere, gave CeF3 nanoparticles of 8–11 nm size. The complex 5 proved to be the best precursor in the series because of the ability of the diglyme ligand to act as capping reagent during decomposition to render the CeF3 particles monodisperse in organic solvents. The obtained CeF3 nanoparticles were characterized by FT-IR, EDX analysis and TEM studies and their luminescence and scintillation responses under UV and X-ray excitation were studied and compared with that of CeF3 single crystal.

Liquid-Crystalline Suspensions of Photosensitive Paramagnetic CeF₃ Nanodiscs

et al. 2019

The design of high-performance energy-converting materials is an essential step for the development of sensors but the elaboration of the bulk materials currently used remains costly and difficult. Therefore, a different approach based on the self-assembly of nanoparticles has been explored. We report on the preparation by solvothermal synthesis of highly crystalline CeF 3 nanodiscs. Their surface modification by bisphosphonate ligands led to stable, highly concentrated, colloidal suspensions in water. Despite the low aspect ratio of the nanodiscs (~ 6), a liquid-crystalline nematic phase spontaneously appeared in these colloidal suspensions. Thanks to the paramagnetic character of the nanodiscs, the nematic phase was easily aligned by a weak (0.5 T) magnetic field, which provides a simple and convenient way of orienting all the nanodiscs in suspension in the same direction. Moreover, the more dilute, isotropic, suspensions displayed strong (electric and magnetic) field-induced orientation of the nanodiscs (Kerr and Cotton-Mouton effects), with fast enough response times to make them suitable for use in electro-optic devices. Furthermore, emission study showed a direct relation between fluorescence intensity and magnetic field induced orientation of the colloids. Finally, with their fast radiative recombination decay rates, the nanodiscs show luminescence properties that compare quite favourably with those of bulk CeF 3 . Therefore, these CeF 3 nanodiscs are very promising building blocks for the development and processing of photosensitive materials for sensor applications.

“…There are two different polymorphs of lead tungstate: one is commonly found stolzite with the tetragonal symmetry and the other one is rarely found raspite with the monoclinic symmetry, which transforms to stolzite irreversibly around 400 • C [20]. Stolzite PbWO 4 with a scheelite structure can be easily synthesized and its excellent properties, such as high density (8.2 g cm −3 ), short decay time (less than 10 ns) and high resistance for radiation damage, etc, have been determined [21,22]. Hence stolzite has been successfully used in laser and stimulated Raman scattering, especially chosen as a promising scintillating medium for the electromagnetic (EM) colorimeter in the Large Hadron Collider (LHC) at CERN [23].…”

A facile, dextran-directed solution route for the morphology- and structure-controlled synthesis of PbWO(4) crystals, such as monoclinic raspite PbWO(4) nanobelts and tetragonal stolzite PbWO(4) crystals with penniform and wheat-ear-like morphologies, has been demonstrated. Three differently charged dextrans were employed for the PbWO(4) crystallization and they turned out to be very effective in the morphological and structural modulation of PbWO(4) crystals, as evidenced by the scanning electron microscopy (SEM), transmission electron microscopy (TEM), x-ray diffraction (XRD) and Raman spectroscopy characterizations. In particular, novel monoclinic raspite PbWO(4) nanobelts were produced under the direction of anionic dextran with a suitable concentration, probably due to the specific interactions between SO(4)(2-) groups from anionic dextran molecules and Pb(2+) ions from PbWO(4) crystals. To the best of our knowledge, this is the first synthesis of monoclinic raspite PbWO(4) in the laboratory, which usually exists as a natural crystal. In addition, the photoluminescence properties of the obtained PbWO(4) crystals with different morphologies and crystal structures have been characterized and discussed, which provides useful information for the fundamental investigation and potential application of PbWO(4) crystals.
