Preparation and characterization of Fe2O3 coating on quartz fabric by electron beam evaporation

摘要

Iron III oxide (Fe2O3) nanoparticles were coated on quartz fabric by electron beam evaporation (EBE) and then annealed in a muffle furnace under air atmosphere at 800 °C for 5 h. The Fe2O3 coated fabric is characterized by energy dispersive X-ray spectroscopy, X-ray diffraction and scanning electron microscopy. The thickness and color performance of the Fe2O3 film on the quartz fabric were measured with a surface profiler and color spectrophotometer, respectively. It is found that an increase of electron beam currents from 20 mA to 60 mA results in an increase of color depth of the coated fabric. The color of the Fe2O3 coated quartz fabric is reddish yellow and changes to red after annealing. The thickness of the Fe2O3 film also increases with the rise of electron beam current.
