【摘要】 以醋酸锌、硫代乙酰胺为原料,P123表面活性剂为模板,采用水热法,成功合成ZnS微球,并提出其可能的形成机理.通过XRD,TEM,FT-IR,N2吸附-脱附表征,发现该微球由ZnS纳米颗粒组成,ZnS纳米颗粒尺寸为6～7nm;微球直径500～600nm,具有单分散性,表面光滑,大小均匀;在4000～400cm-1波段具有热红外透过性等特点,有望在光、电、磁等领域发挥其潜在的应用价值.更多还原

【Abstract】 Zinc sulfide microspheres are synthesized via a hydrothermal method, using surfactant P123 as template, and a possible mechanism of P123 as template for fabricating zinc sulfide microspheres was pro- posed. TEM, XRD, N2 adsorption-desorption isotherms and FT-IR spectra were used for characterization. It shows that the zinc sulfide microspheres with diameter of 500～600 nm is comprised of ZnS nanocrystals with diameter of 6～7 nm. It is not only smooth and round, but also monodispersed. FT-IR spectra show that it is transparent from 4000 to 400 cm-1. Therefore it is potential in many other fields such as optics, electronics, magnetics and so on.更多还原
