Preparation of well uniform-sized and monodisperse ZnS nanoballs by γ-irradiation method

Well uniform-sized and monodisperse ZnS nanoballs with an average diameter about 120 nm were synthesized through γ-irradiation route by controlling appropriate irradiation time under ambient pressure and at room temperature. The products are characterized by field emission scanning electron micrograph (FESEM), transmission electron microscope (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectrometry (XPS). The influencing factors for the uniform-sized ZnS nanoballs e.g. irradiation time (dose), and pressure were also primarily investigated.
