Cores and effect: water‐dispersible core–shell structures and heterostructures incorporating gold nanocrystals of different shapes (polyhedra, cubes, and rods) and a variety of transition metal sulfide semiconductors (zns, cds, nis, ag 2 s, and cus) are synthesized using cetyltrimethylammonium bromide‐encapsulated gold nanocrystals and metal thiobenzoates as starting materials. Generally, if iron oxides were always assumed as the core, its structure can roughly be divided into three types: core-shell, matrix, and shell a-core-shell b as plotted in fig 1 , coating an ensemble of iron oxide nps by organic material yields core-shell nanostructure. Abstract: zinc sulfide (zns), a representative of wide band gap semiconductor nanocrystals, has an excitonic bohr radius (abzns ) of 25 nm it makes zns nanoparticles (zns np) having such size very interesting as small biomolecular probes for fluorescence and laser scanning microscopy.
