The transitional metal (TM)-doped ZnS nanoparticles often display core@shell structures. The magnetic properties of TM-doped ZnS rely heavily on the concentration of the magnetic impurities. The structures, electronic and magnetic properties of first-row TM embedded in the Zn18S18 cages (TMn@Zn18S18, n = 1–3) were studied using first principles. The results show that the Ni2@Zn18S18, Ti3@Zn18S18, V3@Zn18S18, Co3@Zn18S18, and Ni3@Zn18S18 clusters are more structurally stable than the Zn18S18 cages. The TMn clusters obviously improve the chemical reactivity of Zn18S18 cages. The TMn (Cr, Mn, Ni, Cu and Zn; Fe2, Co2, Ni2 and Cu2; Mn3, Co3, Ni3 and Cu3) clusters obtain a few electrons from the Zn18S18 cages. The net spin densities of the TMn@Zn18S18 (TM = Mn, Fe, Co and Ni, n = 1–3) clusters are significantly affected by the number of integrated TM atoms.
