通过真空镀膜法在单晶硅片上制备了一种新的亚酞菁 (三硝基溴硼亚酞菁 )薄膜。利用全自动椭圆偏振光谱仪研究了该薄膜的椭偏光谱 ,测量了其复折射率、复介电常数和吸收系数 ,估算了薄膜在窗口区域的俘获能级并对其吸收谱的成因作了分析。
A new sub-phthalocyanine (trinitrobromoborubicphthalocyanine) thin film was prepared on a monocrystalline silicon wafer by vacuum deposition. The ellipsometry of the film was investigated by using an automatic ellipsometer. The complex refractive index, complex permittivity and absorption coefficient of the film were measured. The trapped energy level of the film in the window region was estimated and its absorption spectrum was analyzed .
