State-of-the-art core@shell multifunctional nanostructures were prepared that are capable to serve the need of magneto/fluorescent characteristics in a single unit. CdS quantum dots (QD’s) shell was successfully developed upon the SrFe ₁₂O₁₉ nanoparticles core surface and a clear add-on was observed from UV–visible spectroscopy, photoluminescence spectroscopy, VSM and FTIR, with high stability and intactness of core and shell. Optical studies provide in-depth information about development of any new phase at the interface and reject all the possibilities of defects or in core@shell structures. Stoner–Wohlfarth value manifests the single magnetic domain structures for the core@shell nanostructures. Uniaxial anisotropy was achieved with single easy direction. Using water for the synthesis augments the applications zone of these nanostructures specifically in the field of biology. This magnet inside semiconductor model fulfil the need of targeting and tracking at the same time and thus proved to be very useful tool in targeted drug delivery, administer as a dual-modal imaging probe for in vivo multi-photon cell-dynamics, MRI; and cell-sorting applications. Different sets of core/shell nanostructures were synthesized to optimize the best Strontium hexa ferrite (SHF) core loading and shell particle size to achieve finest composition with finest “magneto fluorescent” properties.
