Resumen en inglés Structural, morphological and compositional characterizations of zinc selenide (ZnSe) nanoparticles (NPs) are presented. ZnSe NPs have been obtained by colloidal synthesis in aqueous solution using zinc nitrate (Zn(NO3)2) and elemental selenium (Se) as precursors, sodium borohydride (NaBH4) as reducing agent, a solution of sodium hydroxide (NaOH) and pentasodium tripolyphosphate (Na5P3O10) named Extran was used as surfactant. The pH was varied from 8 to 11 and the Zn:Se molar concentration was varied from 3:1 to 1:3. A cleaning process was applied to eliminate the by-products using hydrochloric acid (HCl). ZnSe NPs exhibit a cubic zinc-blende structure. The NPs size was estimated between 4.9 nm and 3.0 nm and depends on molar concentration
