Research Abstract

Europium sulfide (EuS) nanocrystals have great potential in such applications as novel photo-isolators for optical fibers and photo-magnetic devices. The cube-shaped EuS nanocrystals are prepared by the thermal reduction of single source precursor, tetra (diethyldithiocarbamate) europium complex with oleylamine as a surface modified regent. In the present study, three-dimensional Superlattice structures (SLSs) assembled with cube-shapedEuS nanocrystals (NCs) and their remarkable magnetic properties have been successfully observed.
