Magnetic and photoluminescence properties of Fe3O4@SiO2@YP1−xVxO4:Dy3+ nanocomposites

Luminescence and magnetic properties of novel nanoparticle-sheathed 3D Micro-Architectures of Fe0.5R0.5(MoO4)1.5:Ln3+ (R = Gd3+, La3+), (Ln = Eu, Tb, Dy) for bifunctional application

“…However, the existence of magnetic iron (Fe 3+ ) in the scheelite-type Fe 0.5 Gd 0.5 (MoO 4 ) 1.5 structure considerably reduces their luminescence, as Fe 3+ ions share the dodecahedral sites with Gd 3+ /Ln 3+ . [7,25,26] Further, the photoluminescence properties of Fe 0.5 La 0.5 (MoO 4 ) 1.5 : Ln 3+ are similar to that those of Fe 0.5 Gd 0.5 (MoO 4 ) 1.5 :Ln 3+ and do not show any remarkable variation ( Fig. 8(b)).…”

“…This property can be used for sensitive labels for imaging human and animal cells, tissues, and other biomedical applications (in vitro and in vivo). [6,7] In addition, selecting a suitable host matrix with peculiar properties is important for determining the colour tunable emission properties of the particles, as well as their magnetic properties depending on the kind of application in question. Mostly, iron-based core-shell micro/nanostructures are used for bi-functional magnetic and luminescence applications.…”

Synthesis, Characterization and Cytotoxicity of Novel Multifunctional Fe3O4@SiO2@GdVO4:Dy3+ Core-Shell Nanocomposite as a Drug Carrier

“…The magnetic Fe 3 O 4 nanoparticles were prepared according to a previously reported synthetic process [19]. Typically, FeCl 3 ·6H 2 O (1.3495 g) and NaAc (7.1926 g) were dissolved in EG solution (40 mL).…”

“…The previous investigation results indicated that nanosized GdVO 4 :Ln 3+ phosphors have a significant application in a high definition flat display panels and potential applications in biology [16,17,18,19]. Compared with Ln 3+ -activated YVO 4 , GdVO 4 :Ln 3+ exhibits highly efficient emitting phosphors, in which the energy transfers from the GdVO 4 host to the incorporated Ln 3+ ions through V 5+ –O 2− charge transfer (CT), yielding an efficient luminescence of Ln 3+ activators.…”

Synthesis, Luminescence and Magnetic Properties of Novel Fe0.5Gd0.5(MoO4)1.5:Eu3+ Micro/Nano (3D) Structures

“…The phosphor particles can be magnetically directed, aligned, tracked, after applying the external magnetic fields. Subsequently, their luminescence can be visualized under optical excitation, which can be used widely for biological labeling, imaging of human and animal cells, tissues, and in vitro, in vivo applications [22,25].
