以无水氯化锰、硫磺粉和硼氢化钾为原料，乙二醇为溶剂，在150-180 °C下，采用溶剂热法制备了亚稳纤锌矿结构的γ-MnS空心球。采用X射线衍射、X射线光电子能谱、场发射扫描电子显微镜、扫描电子显微镜、透射电子显微镜和光致发光等手段对亚稳γ-MnS和稳定α-MnS进行了表征。实验表明，反应温度、溶剂、还原剂浓度和还原度是影响产物物相的关键因素。提出了空心球生长的可能机制。（© Wiley-VCH Verlag GmbH & Co. KGaA，69451魏因海姆，德国，2005）
A solvothermal route has been developed to prepare metastable wurtzite-structure γ-MnS hollow spheres from anhydrous manganese chloride, sulfur powder, and potassium borohydride in ethylene glycol at 150–180 °C. The metastable γ-MnS and stable α-MnS were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, field-emission scanning electronic microscopy, scanning electron microscopy, transmission electron microscopy, and photoluminescence. Experiments show that the reaction temperature, the solvent, and the concentration and reducibility of the reductant are the crucial factors affecting the phase of the product. A possible growth mechanism for the hollow sphere is proposed. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
