“…Unexpectedly, we observe the broad bands between 3250 and 3750 cm -1 and 1250-1600 what confirm the presence of the molecules H 2 O on the surface. The same low temperatures synthetic method applied for LaPO4:Eu 3+gives an access to anhydrous nanophosphates with excellent photophysical properties[6,11]. The absence of water and hydrous compounds was confirmed by IR spectroscopy.…”

“…The studied nano-powdered samples were synthesized according the procedure described earlier in [6,11]. In this synthesis protocole lanthanides precursors, which are the simple lanthanide salts like nitrate or acetate hydrates are converted at relatively low temperature (~140°C) to anhydrous lanthanide phosphate.…”

“…This is why we would like to perform the studies of Nd 3+ activated LaPO 4 prepared by using earlier reported method of synthesis of nanoscale orthophosphate with ILs, which allow to synthetized anhydrous materials at relatively low temperature. The Eu 3+ ions doped materials showed relatively high luminescence, and the impurity traces did not efficient quench luminescence [6,11]. We applied above preparation protocol to synthetize LaPO 4 :Nd 3+ materials, in aim to study the influence of ILs on the morphology of obtained particles on their NIR emission performance.…”

Monoclinic monazite-type Nd 3+-doped lanthanum orthophosphate (LaPO 4 :Nd 3+) nanoparticles were prepared by microwave treatement of simple lanthanide precursors such as Nd(OAc) 3 •xH2O, OAc = acetate) with task-specific dihydrogen phosphate ionic liquids (ILs) 1-butyl-1-methylpyrrolidinium dihydrogenphosphate-BmPyrH 2 PO 4 (IL 1) and 2hydroxyethyl-N,N,N-trimethylammonium, [choline][H 2 PO 4 ] (IL2) as the reaction medium, reactant and in-situ nanoparticle stabilizer and templates at 140°C within 10 minutes. This synthesis route possesses many advantages as it is a fast and facile preparation method for the desired phosphate nanomaterials without the necessity for post-reaction heat treatment to obtain the anhydrous high temperature monazite phosphate phase. The nano-sized phosphors Nd 3+ :LaPO 4 were carefully analyzed by the powder X-ray diffraction, electron microscopy and spectroscopic techniques taking advantage of the Nd 3+ spectroscopic probe to analyze in detail the structural properties. Applied high resolution low temperature absorption and emission techniques allowed to complete the structural information unavailable from the XRD powder patterns. A clear influence of the used task-specific dihydrogen phosphate ILs on the structure, morphology, luminescence intensity and lifetimes of the obtained Nd 3+ :LaPO 4 was found. It is worth noting that the Nd 3+ luminescence in LaPO 4 has never been reported up to now.

“…Using a combination of microwave irradiation and ILs, other complex metal structures with enhanced performance were synthesized. Cybinska et al prepared Ln 3+ -doped (Ln = Sm, Eu, Tb, Dy) BiPO 4 NPs with particle sizes <10 nm from the respective metal acetates and choline or butylammonium dihydrogen-phosphate in a microwave at 120 °C for 10 min [76]. In their work, ILs acted as a solvent, microwave susceptor and reaction stabilizer; they also affected particle morphology and size.…”

During recent years, synthetic methods combining microwaves and ionic liquids became accepted as a promising methodology for various materials preparations because of their high efficiency and low energy consumption. Ionic liquids with high polarity are heated rapidly, volumetrically and simultaneously under microwave irradiation. Hence, combination of microwave irradiation as a heating source with ionic liquids with various roles (e.g., solvent, additive, template or reactant) opened a completely new technique in the last twenty years for nanomaterials and polymers preparation for applications in various materials science fields including polymer science. This review summarizes recent developments of some common materials syntheses using microwave-assisted ionic liquid method with a focus on inorganic nanomaterials, polymers, carbon-derived composites and biomass-based composites. After that, the mechanisms involved in microwave-assisted ionic-liquid (MAIL) are discussed briefly. This review also highlights the role of ionic liquids in the reaction and crucial issues that should be addressed in future research involving this synthesis technique.

“…However, volatile organic compounds have hazardous impacts on flora and fauna. To overcome these issues, ionic liquid (IL) assisted methods have been developed as they have high thermal and chemical stability, less volatility, and tunable physicochemical properties, which make them superior to conventional organic solvents (Rogers and Seddon, 2003;Wilkes, 2004;Plechkova and Seddon, 2008;Cybinska et al, 2016). Therefore, ILs are also known as "green" and "designer" solvents (Rogers and Seddon, 2003;Plechkova and Seddon, 2008;Duan et al, 2014).…”

Lanthanide (Ln3+) ion(s)-doped or rare-earth ion(s)-doped nanomaterials have been considered a very important class of nanophosphors for various photonic and biophotonic applications. Unlike semiconductors and organic-based luminescent particles, the optical properties of Ln3+-doped nanophosphors are independent of the size of the nanoparticles. However, by varying the crystal phase, morphology, and lattice strain of the host materials along with making core-shell structure, the relaxation dynamics of dopant Ln3+ ions can be effectively tuned. Interestingly, a judicious choice of dopant ions leads to unparallel photophysical dynamics, such as quantum cutting, upconversion, and energy transfer. Recently, ionic liquids (ILs) have drawn tremendous attention in the field of nanomaterials synthesis due to their unique properties like negligible vapor pressure, nonflammability, and, most importantly, tunability; thus, they are often called “green” and “designer” solvents. This review article provides a critical overview of the latest developments in the ILs-assisted synthesis of rare-earth-doped nanomaterials and their subsequent photonic/biophotonic applications, such as energy-efficient lighting and solar cell applications, photodynamic therapy, and in vivo and in vitro bioimaging. This article will emphasize how luminescence dynamics of dopant rare-earth ions can be tuned by changing the basic properties of the host materials like crystal phase, morphology, and lattice strain, which can be eventually tuned by various properties of ILs such as cation/anion combination, alkyl chain length, and viscosity. Last but not least, different aspects of ILs like their ability to act as templating agents, solvents, and reaction partners and sometimes their “three-in-one” use in nanomaterials synthesis are highlighted along with various photoluminescence mechanisms of Ln3+ ion like up- and downconversion (UC and DC).
