Facile synthesis of flower like FePt@ZnO core-shell structure and its bifunctional properties

Flower shaped FePt and ZnO coated FePt with core-shell nanostructures are synthesized by a facile solvothermal procedure. Shell thickness of ZnO over FePt core was tuned by varying FePt concentration with respect to ZnO. Hybrid structure with lower FePt concentration exhibited bifunctionality such as near room temperature ferromagnetism and photoluminescence. Pristine FePt crystallize in the fct (L10) phase whereas it converts into fcc phase in presence of ZnO.
