“…9 Among these anions are molybdates, which absorb UV light that can be transferred to some Ln 3+ ions such as Eu 3+ , Dy 3+ or Tb 3+ . 10 Because of this, a large variety of phosphors have been developed mostly based on different kinds of lanthanide 11 or alkaline earth [12][13][14][15] molybdates doped with Ln 3+ cations.…”

CrystEngComm publishes novel findings in the field of crystal engineering, including properties, target crystals and materials, crystal growth, nanocrystals and computational studies. Articles reporting results which could be routinely predicted or result from the application of standard procedures or techniques are unlikely to prove acceptable. For publication in CrystEngComm a paper must report work of high quality and originality. Communications must report chemistry of sufficient importance and impact to justify preliminary publication. Papers should report more complete studies.

“…Judicious selection of host material is very important for tuning the photophysics of RE 3+ dopant ions (Sharma et al, 2017a). Numerous types of host materials have been explored to date, including oxides, phosphates, fluorides, vanadate, and borate (Sun and Zheng, 2010;Tian et al, 2012;Tian et al, 2014;Kuzmanoski et al, 2015;Alammar et al, 2016;Cybinska et al, 2016;Chouryal et al, 2021). Important points have to be considered before selecting the host material like thermal and chemical stability, low phonon energy, high refractive index, and large bandgap (Gai et al, 2014;Sharma et al, 2017a).…”

“…Therefore, several host materials have been explored for doping of Ln 3+ ions, including alkali/alkaline/ lanthanide-based binary/ternary fluorides, lanthanide orthophosphates (LnPO 4 ), and oxides (Ln 2 O 3 ) (Guo et al, 2010;He et al, 2012;Jiang et al, 2012;Alammar et al, 2016;Cybińska et al, 2016;Sharma et al, 2017a;Zhao et al, 2018). In order to prepare the aforementioned host materials, numbers of synthesis methods, such as sol-gel, thermal decomposition, hydrothermal/solvothermal, microwave-assisted, sonochemicalassisted techniques, should be readily employed (He et al, 2011a;Gai et al, 2014;Kuzmanoski et al, 2015;Alammar et al, 2016;Sharma et al, 2017a). Eventually, during the synthesis, various types of structure-controlling agent(s) and volatile organic compounds are used for tuning the size, morphology, crystal phase of prepared nanophosphors so that desired materials can be synthesized (Gai et al, 2014;Sharma et al, 2017a).…”

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).
