✦ Synopsis

Nickel sulfide uniform hollow spheres (see scanning electron microscopy image, Figure) have been successfully synthesized by γ‐irradiation of a PMMA–CS~2~–ethanol aqueous solution that contains NiSO~4~·6H~2~O at room temperature. Calculation shows that the diameter of the NiS hollow spheres is 500 nm and the thickness of shell is ∼ 20 nm. A possible growth mechanism is also presented.
