Abstract
A 5 at.% Dy3+ ions doped CaWO4 nanoparticles (CaWO4:5Dy) were synthesized by hydrothermal
method using polyethylene glycol (PEG) as solvent medium and capping agent. The phase purity and
crystalline properties of the prepared nanoparticles were obtained from the XRD analysis. TEM images
revealed that the CaWO4:Dy3+ have particles of size approximately in the range 30-50 nm. The prepared
magnetic luminescence nanocomposite exhibits a high saturation magnetization. The prepared
nanocomposite can achieve hyperthermia temperature (42 ºC) in a short period by applying the
alternating magnetic field, externally. The nanocomposite also shows photoluminescence properties.
Nanomaterials described in this work can be used for optical imaging as well as hyperthermia
applications.
