摘要

采用化学喷雾热解（CSP）方法，在400°C左右的玻璃基板恒温下制备了二硫化铁（FeS2）和Mn掺杂的薄膜。根据XRD检查，薄膜在结构上是立方取向的，具有主要的平面取向（201）。FeS2基体中Mn离子的掺杂通过衍射峰向较低的2θ值的微小偏移得到证实。根据AFM的研究，制备的黄铁矿薄膜的表面是均匀的。根据XRD数据，预测的晶粒尺寸随着一致性锰的增加而改变。当与未掺杂的FeS2薄膜相比时，Mn2+掺杂的FeS2-薄膜的期望带隙能量显示出红移。

Synthesis and characterization of manganese-doped FeS2 thin films via chemical spray pyrolysis

A thin film of iron disulfide (FeS2) and Mn-doped was prepared using the chemical spray pyrolysis (CSP) method at a constant temperature of the glass substrate at around 400 °C. According to XRD examination, films were structurally cubic oriented with a predominant planar orientation (201). The doping of Mn ions in the FeS2 host matrix was confirmed by a minor shift of the diffraction peak towards the lower 2θ values. The surface of the produced film for pyrite was homogeneous, according to the AFM investigations. According to the XRD data, the predicted grain size altered as the consistent manganese increased. When compared to undoped FeS2 thin films, the Mn2+- doped FeS2 thin films' desired bandgap energy showed a red shift.
