Magnetic and luminescent properties of Fe/Fe3O4@Y2O3:Eu nanocomposites

The influence of precursors on phase evolution of nano iron oxides/oxyhydroxides: optical and magnetic properties

“…2,3 Various applications of iron oxide nanomaterials (NMs) are in the field of catalysis, sensors, pigments, adsorbents, enzyme supports, ferrofluids and magnetic materials. [4][5][6][7][8][9][10][11][12][13][14] The synthesis routes include hydrothermal, sol-gel, solvothermal, mechanochemical, co-precipitation-annealing, thermal decomposition, microwave plasma, microemulsion and surfactant mediation etc. [15][16][17][18] The experimental parameters for the synthesis of nano iron oxides play a key role in determining the size distribution, morphology, magnetic properties and surface chemistry.…”

Novel Electrospun Dual-Layered Composite Nanofibrous Membrane Endowed with Electricity–Magnetism Bifunctionality at One Layer and Photoluminescence at the Other Layer

“…Fe 3 O 4 nanoparticles (NPs) are commonly used magnetic material because of their excellent magnetism and biocompatibility . Recently, some types of nanomaterials possessing photoluminescent-magnetic bifunctionality have been reported, which benefit many technical areas such as magnetic resonanece, cell separation, drug targeting, and biological imaging. − As the popular conducting polymers, polyaniline (PANI) has been widely researched and applied in many areas like secondary batteries, electromagnectic interference (EMI) shielding, and catalysts because of its light weight, low cost, tunable conductivity, and environmental stability. , By now, trifunctional Eu­(BA) 3 phen/PANI/Fe 3 O 4 /PVP hollow nanofibers fabricated by electrospinning process are emerged in the literature . In view from previous work by us and other researchers, as for the luminescent-electrical-magnetic trifunctional materials, the luminescent intensity of RE compounds will greatly decline if the RE compounds directly contact with deep-colored materials like Fe 2 O 3 , Fe 3 O 4 , and PANI. , Therefore, it is urgently needed to find a new way of effectively isolating luminescence materials from Fe 2 O 3 , Fe 3 O 4 and PANI.…”

Microstructure and Optical Properties of SPION/Sr3V2O8:Er3+, Yb3+ Nanocomposites Synthesized by Microwave-Assisted Metathetic Method

“…In recent years, bifunctional nanocomposites that exhibit significant magnetic moment and luminescence have attracted much attention because of various applications in biotechnology, medicine and quality inspection. Bifunctional nanocomposites containing the superparamagnetic iron oxide nanoparticles (SPIONs) incorporated into photoluminescent composites could provide novel characteristics via the integration of fluorescent and magnetic properties, offering new potential in a wide range of applications in biomedical systems, such as targeted drugs, diagnostics, therapeutics and bio-imaging [1][2][3] .…”
