NaYF4doped
NaYF₄:doped refers to a family of inorganic nanomaterials based on sodium yttrium fluoride (NaYF₄) that have been doped with lanthanide ions or other transition metal ions to modify their optical, magnetic, or catalytic properties. These nanoparticles are widely studied for their applications in biomedical imaging, optoelectronics, and photonics due to their unique luminescent and photostable characteristics.
The host lattice of NaYF₄ is a hexagonal (β-phase) or cubic (α-phase) crystal structure, with the β-phase
Common dopant combinations include Yb³⁺/Er³⁺ and Yb³⁺/Tm³⁺, which exhibit distinct emission spectra in the visible range.
NaYF₄:doped nanoparticles are also explored for their magnetic resonance imaging (MRI) contrast enhancement when doped with
