Facile one-pot hydrothermal synthesis and structural characterization of transition metals (Cu,Co and Mn) doped ZnS nanoparticles in HMTA matrix

Transition metals (cu,co and mn) doped zns nanoparticles have been prepared by a facile one-pot hydrothermal method using hexamethylenetetramine (hmta),a non-toxic surfactant in aqueous solution. the structural properties of the prepared samples were studied using xrd,tem,sem and ftir analysis. x-ray diffraction (xrd) studies show that the average grain size of the prepared zns nanoparticles is around 2 nm with cubic zinc blende structure and doping of transition metals has no effect on the crystal structure. tem results showed that the synthesized nanoparticles were uniformly dispersed in the hmta matrix without aggregation. formation of hmta stabilized zns nanoparticles were confirmed by ftir studies.
