采用简单的溶剂热法合成了锰掺杂的ZnS（MnxZn 1-xS）纳米棒。合成的纳米棒是单晶的。锰掺入ZnS晶格诱导从六方纤锌矿到立方锌尖晶石结构的相变。纳米棒的直径随着Mn浓度的增加而增大。纳米棒在585 nm附近发出强烈的橙子光。六线超精细分裂观察到的EPR谱中较低的Mn浓度，而广泛的洛伦兹形EPR谱得到较高的Mn浓度，因为在较高的Mn浓度的Mn-Mn团簇的形成。
Manganese-incorporated ZnS (MnxZn1-xS) nanorods were synthesized by a simple solvothermal process. Synthesized nanorods were single crystalline. Manganese incorporation in the ZnS lattice induces a phase transformation from hexagonal wurtzite to cubic zinc blende structure. The diameter of the nanorods increased with the increase of Mn concentration. Intense orange luminescence at similar to 585 nm was observed for the nanorods. Six-line hyperfine splitting was observed in the EPR spectra for lower Mn concentrations, whereas broad Lorentzian-shaped EPR spectra were obtained for higher Mn concentrations because of the Mn-Mn cluster formation at higher Mn concentrations.
