通过电泳沉积 (EPD) 工艺，将 Cs2Mo6Br14 簇前驱体分散在甲乙酮 (MEK) 中的悬浮液在氧化铟锡 (ITO) 涂层玻璃板上制备出具有显着光学性能的薄而透明的 Mo6 簇薄膜。两种聚二甲基硅氧烷（PDMS）；即选择动力粘度分别为1.5和2厘沲的KF-96L-1.5CS和KF-96L-2CS在EPD后对Mo6簇膜进行面涂。通过场发射扫描电子显微镜（FE-SEM）、能量色散光谱（EDS）、傅里叶变换红外光谱（FT-IR）和紫外-可见-近红外（UV-Vis-NIR）光谱表征了PDMS对Mo6团簇薄膜的耐久性、化学相容性和光吸收性能的影响。稳定的PDMS涂层Mo6簇膜在环境条件下可以保存6个月以上。
Thin and transparent Mo6 cluster films with significant optical properties were prepared on indium tin oxide (ITO)-coated glass plates from the suspension of Cs2Mo6Br14 cluster precursors dispersed in methyl-ethyl-ketone (MEK) by an electrophoretic deposition (EPD) process. Two kinds of polydimethylsiloxanes (PDMS); i.e., KF-96L-1.5CS and KF-96L-2CS corresponding to the kinetic viscosity of 1.5 and 2 centistokes, respectively, were selected to topcoat the Mo6 cluster film after the EPD. The influence of the PDMS on the durability, chemical compatibility and light absorption property of Mo6 cluster films were characterized by means of field-emission scanning electron microscopy (FE-SEM), energy dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FT-IR), and ultraviolet-visible-near infrared (UV-Vis-NIR) spectroscopy. The stabilized PDMS-coated Mo6 cluster film could be stored for more than 6 months under ambient conditions.
