ZnS materials have been widely used in fluorescence biosensors to characterize different types of stem cells due to their excellent fluorescence effect. In this study, ZnS was prepared by vulcanizing nano-Zn particles synthesized using a DC arc plasma. The composition and structure of the ZnS materials were studied by X-ray diffraction (XRD), and their functional group information and optical properties were investigated by using IR spectrophotometry and UV-vis spectrophotometry. It has been found that the synthesized materials consist of Zn, cubic ZnS, and hexagonal ZnS according to the vulcanization parameters. Crystalline ZnS was gradually transformed from a cubic to a hexagonal structure, and the cycling properties first increase, then decrease with increasing sulfurization temperature. There is an optimal curing temperature giving the best cycling performance and specific capacity: the material sulfurized thereat mainly consists of cubic β-ZnS phase with a small quantity of Zn and hexagonal α-ZnS. The cubic phase ZnS has better conductivity than hexagonal ZnS, as evinced by electrochemical impedance spectroscopy (EIS). The ZnS (as prepared) shows board absorption, which can be used in fluorescence biosensors in cell imaging systems.

用于荧光生物传感器的硫化锌的结构和性能研究

硫化锌材料由于其优异的荧光效应而被广泛应用于荧光生物传感器以表征不同类型的干细胞。在这项研究中，硫化锌是通过硫化使用直流电弧等离子体合成的纳米锌颗粒来制备的。通过X射线衍射（XRD）研究了ZnS材料的组成和结构，并通过红外分光光度法和紫外-可见分光光度法研究了它们的官能团信息和光学性质。已经发现，根据硫化参数，合成材料由Zn、立方ZnS和六方ZnS组成。结晶硫化锌从立方结构逐渐转变为六方结构，循环性能随着硫化温度的升高先增大后减小。β -ZnS 相，含有少量 Zn 和六方α -ZnS。电化学阻抗谱 (EIS) 表明，立方相 ZnS 比六方 ZnS 具有更好的导电性。ZnS（如制备的）显示板吸收，可用于细胞成像系统中的荧光生物传感器。
