Lanthanide-based hybrid nanostructures: Classification, synthesis, optical properties, and multifunctional applications

Progress in the preparation of Prussian blue-based nanomaterials for biomedical applications

“…Hybrid nanostructures are a class of functional materials with a wide range of applications, and structural control has been shown to have multiple uses to optimize the functions and properties of nanomaterials. 117,118 Organic polymers play an important role in the synthesis of hybrid nanomaterials, so they This journal is © The Royal Society of Chemistry 2023 play a huge role in the preparation of PBNPs. [119][120][121][122][123] In terms of external modification, when materials such as PVP, 25 chitosan, 124 and citric acid 125 are used as reducing agents, dispersants and protective agents, they are often wrapped on the surface of PB to provide some modification points or give them better dispersibility and biological compatibility.…”

Recent advances in rare earth ion‐doped upconversion nanomaterials: From design to their applications in food safety analysis

“…In reality, UCNPs are perfect energy donors; however, unique recognition groups (energy acceptors) must be applied to the surface of UCNPs in order to accomplish extremely efficient FRET (Gu & Zhang, 2018). QDs are well suited as a component for FRET‐based sensing devices due to their broadband absorbance, limited emission bands, and high quantum yield (Singh et al., 2022). Furthermore, noble metal nanoparticles such as gold nanoparticles (AuNPs), silver nanoparticles (AgNPs), and Au–Ag hybrids have gained significant momentum as FRET acceptors for UCNPs due to their superb photophysical features and great biocompatibility.…”

Lanthanides: The Key to Durable and Sustainable Corrosion Protection

“…The lanthanide group elements (Ln), also known as rare earth elements (REEs), are the “nutrients” of metals and “vitamins” of modern industry and have the ability to improvise the intramural aspects of metals (alloy formation, hardness, and strength) and have been extensively employed in various fields including microelectronics, aeronautics, automotive, medical, chemical, and metallurgical engineering. , Furthermore, the novelty of Ln having unpaired electrons in f-orbitals also intercalates an influential impact on extraneous properties of metals by depositing on the surface. , With deposition, the limited radial extension affiliated with these f-orbitals, having a negligible effect on the chemistry of the interaction process, provides multiple ways and reaction sites to intermingle with the substrate surface . The half-filled orbitals connected with paramagnetic, diamagnetic, and ferromagnetic behavior additionally insert electromagnetic and optical properties in the lanthanides. , Accompanying all these aspects, coatings of Ln elements have been recently adopted as an effective replacement for highly toxic and carcinogenic chromate coatings that have the ability to modify both the physical and chemical properties of metals. − There is striving to search for chromate-free coatings that resulted in many procedures that involved phosphate, molybdates, silicates, titanium, and borate coating procedures, which produced both types of positive and negative alterations in surficial properties .…”
