A study on sy nthesis of magnetic iron oxid e core / Z nS shell n anopartic les

In the past decad e or so, co re/shell str uctured nanoparticles have been r eceiving gro wing research attention , due to t heir enhanced or com bined optic al, electronic, and ma gnetic prope rties compa red to the single-compo nent nanom aterials. Interests in n anocomposites of this kind originate not only from the curio ities of scientities who are exploring the mesoscopic world, but also fr om the ever in creasing demands placed on materials synth esis perfor mance by nanotechnolog y. Although much progress has been made in syntheses of core/shell nanoparticles[۱,۲]. In a recen t report, w e described the synthesis of magn etic nanopar ticles iron oxide/ZnS c ore-shell na noparticles. Scan electr on microscopy (SEM) and Transmission electr on microscopy (TEM) shows whether particle s of ZnS character con tains a ma gneticcore or not.
