Half a century after its initial emergence, lanthanide photonics is facing a profound remodeling induced by the upsurge of nanomaterials. Lanthanide-doped nanomaterials hold promise for bioapplications and photonic devices because they ally the unmatched advantages of lanthanide photophysical properties with those arising from large surface-to-volume ratios and quantum confinement that are typical of nanoobjects. Cutting-edge technologies and devices have recently arisen from this association and are in turn promoting nanophotonic materials as essential tools for a deeper understanding of biological mechanisms and related medical diagnosis and therapy, and as crucial building blocks for next-generation photonic devices. Here, the recent progress in the development of nanomaterials, nanotechnologies, and nanodevices for clinical uses and commercial exploitation is reviewed. The candidate nanomaterials with mature synthesis protocols and compelling optical uniqueness are surveyed. The specific fields that are directly driven by lanthanide doped nanomaterials are emphasized, spanning from in vivo imaging and theranostics, micro-/nanoscopic techniques, point-of-care medical testing, forensic fingerprints detection, to micro-LED devices.

Upconversion (UC) is a powerful mulitphoton mechanism that converts low-energy photons into higher energy emission. One of the most investigated UC systems is upconverting phosphors (UCPs). Here, a new, one-pot synthetic procedure was used to prepare water dispersible, visibly emissive, rare-earth doped UCPs that were capped with the functional groups oleic acid (OA), 6-aminohexanoic acid (AHA), and 6-maleimidohexanoic acid (MHA). These synthesized UCPs were characterized by UC luminescence, dynamic light scattering (DLS), transmission electron microscopy (TEM), and powder Xray diffraction (pXRD). This study expands upon our previous

pacitors, and sensors due to the enhanced properties arising from the nanobuilding blocks and the way they are arranged. [2] Hollow hierarchical and porous microand nanostructures have attracted significant attention because of their interesting features, like low densities, large interior spaces, high specific surface areas with a broad range of potential applications in the fields of water treatment, energy conversion, gas sensing, catalysis, and drug delivery. [3] Similarly, synthesis of cube-like morphology also gained importance due to its structure and crystal facet exposure which helps in improving the properties such as gas sensing and catalysis. [4] The rare-earth ions doped micro/nanoparticles have enticed researchers because of their broad range of applications in solid-state light-emitting diodes and other optoelectronic devices. [5] In conjunction with the utilization in illumination devices, they are also used as fluorescent labels in biological applications. [6] Among different rare-earth doped materials, fluoride micro/nanoparticles have got more significant importance compared to other materials like oxides, carbonates, vanadates, and garnets, owing to their unique optical properties. [7] The materials show low toxicity, high photochemical stability, and long lifetime. Moreover, fluoride-based materials have low phonon energy (<350 cm −1 ) which reduces the nonradiative relaxation and are expected to improve the quantum efficiency. [8] Although there are lots of reports on rare-earthbased (Y, Ln) fluoride materials, when the rare-earth cations are replaced with Bi 3+ ions, they become more beneficial in economic viewpoint because of their ease of availability, good purification, and low cost, as compared with the rare-earths. Despite many advantages, like their use as cathode materials for batteries and photocatalysis, few reports were found about bismuth-based fluoride materials. [9] Zhao et al. reported the size and shape controlled synthesis of BiF 3 through solvent extraction route. [10] Likewise, Sarkar et al. reported the Ln 3+ doped BiF 3 nanoparticles enclosed in polymer matrix and explained the importance of poly (vinyl pyrrolidine) in reducing the size of the particle. The upconversion and downconversion optical properties were also studied by doping Yb 3+ /Er 3+ and Eu 3+ , respectively. [11] In addition, Escudero et al. reported the BiF 3 synthesis of quasispheres, and the spheres were of few µm size. [12] Recently, Feng et al. demonstrated the photocatalytic activity of BiF 3 particles under visible light illumination. [13] To the best of our knowledge, there were no reports found on the A facile approach for shape-tunable synthesis of bismuth fluoride nanoparticles is reported. The approach is based on the homogeneous precipitation of precursor materials in mixed solvents (H 2 O and ethylene glycol) and only ethylene glycol. The influencing factors on the morphology of the particles, i.e., solvent ratio, F/Bi ratio, and ethylenediaminetetraacetic acid, are studied in detail, a...
