Obtaining and characterization of ZnSe nanoparticles from aqueous colloidal dispersions

Structural, morphological and compositional characterizations of zinc selenide (ZnSe) nanoparticles (NPs) are presented. ZnSe NPs have been obtained by colloidal synthe sis in aqueous solution using zinc nitrate (Zn(NO 3 ) 2 ) and elemental selenium (Se) as precursors, sodium borohydride (NaBH 4 ) a...
