“…We have used, in the present study, a strategy based on the controlled release of fluoride anions using an ionic liquid ([BMIM]BF 4 ) as fluoride precursor and two different lutetium salts (lutetium acetate hydrate and lutetium nitrate hydrate), the latter providing two different particle morphology. The required fluoride anions are liberated by the ionic liquid as a consequence of its hydrolysis with the hydration water molecules of the lutetium precursor (Jacob et al 2006). Ionic liquids are non-volatile, non-flammable, and thermally stable organic salts with low melting point, which show a superior capability for the solvation and stabilization of metal ions, which gives to them the possibility of acting as capping agents or surfactants.…”

A simple procedure for the synthesis of orthorhombic, uniform, LuF 3 particles with two different morphologies (rhombus-and cocoon-like) and nanometer and sub-micrometer size, respectively, is reported. The method consists in the aging, at 120°C for 2 h, a solution containing [BMIM]BF 4 ionic liquid (0.5 mL) and lutetium acetate (in the case of the rhombi) or lutetium nitrate (in the case of the cocoons) (0.02 M) in ethylene glycol (total volume 10 mL). This synthesis method was also adequate for the synthesis of Eu 3? -doped LuF 3 particles of both morphologies, whose luminescence properties were investigated in detail. The experimental observations reported herein suggest that these materials are suitable phosphors for optoelectronic as well as in vitro biotechnological applications.

“…It was well known that PF 6 À hydrolyzes to produce F À , HF, POF 3 , and so on [9]; BF 4 À hydrolyzes to form F À , HOBF 3 À , HF, and H 3 BO 3 [10][11][12] under proper conditions. Although no additional water was added into the system, the anions in the mixture were also hydrolyzed as a result of the trace water and hydration water of Ln(NO 3 ) 3 · 6H 2 O.…”

The shape control of nano-and microcrystals has received considerable attention because the morphology, dimensionality, and size of materials are well known to have great effects on their physical and chemical properties, as well as on their applications in optoelectronic devices. Ionic liquids were found to be very advantageous in synthetic nanochemistry, especially as templates and capping agents. Their particular phase behavior and unique physicochemical properties, including complex solvation interactions with organic and inorganic compounds, can provide various growth pathways for nanocrystals with novel morphologies and properties. This chapter gives an overview of existing ionic liquid-assisted hydrothermal method for the synthesis of rare earth luminescence materials. Particular attention is given to synthesis mechanism and the role of ionic liquids in the formation of specific morphology, as well as the effect of morphology on the luminescent properties.

“…GdF 3 nanocubes have been synthesized in a similar way from gadolinium chloride and the ionic liquid (IL) [BMIM]BF 4 in DEG [54]. In this case [BMIM]BF 4 slowly releases fluoride anions by hydrolysis [93]. It is important to mention that the use of ILs has been suggested as a green alternative to the conventional organic solvents for the synthesis of inorganic compounds [94,95] [96], and rhombic-like LuF 3 NPs, obtained after a solvothermal process at 150°C of ethanolic solutions containing the corresponding RE nitrates and 1-octyl-3-methylimidazolium hexafluorophosphate (OmimPF 6 ) [97].…”

Abstract:Rare earth based nanostructures constitute a type of functional materials widely used and studied in the recent literature. The purpose of this review is to provide a general and comprehensive overview of the current state of the art, with special focus on the commonly employed synthesis methods and functionalization strategies of rare earth based nanoparticles and on their different bioimaging and biosensing applications. The luminescent (including downconversion, upconversion and permanent luminescence) and magnetic properties of rare earth based nanoparticles, as well as their ability to absorb X-rays, will also be explained and connected with their luminescent, magnetic resonance and X-ray computed tomography bioimaging applications, respectively. This review is not only restricted to nanoparticles, and recent advances reported for in other nanostructures containing rare earths, such as metal organic frameworks and lanthanide complexes conjugated with biological structures, will also be commented on.
