Rod‐Shaped Assemblies of FePt‐PtTe₂ through Dynamic Templating

Abstract

Rod-shaped assemblies of FePt nanoparticles embedded amidst PtTe2 nanoplatelets, formed by co-precipitation in the presence of sucrose and trioctylphosphine oxide. The (001) planes in each of the PtTe2 nanoplatelets are stacked along directions close to the nanorod axis. Separate precipitation of FePt or PtTe2 under identical conditions yield spheres or randomly shaped clusters platelets, underscoring the key influence of co-precipitation on the morphology of the nanostructure assembly.
