摘　　要：在研究用射频磁控共溅射法制备的不同体积含量的Au-MgF2纳米金属陶瓷复合薄膜/Si基片系统的红外光谱特性时发现:薄膜的红外光谱存在振荡现象,同时在振荡的红外光谱中出现明显的包络线,这些现象对薄膜的光学特性分析带来一定困难。定性和定量分析表明这两种现象均由光透过基片产生的多光束干涉引起,并给出了消除此现象的方法。In the infrared spectra analysis of Au - MgF2 nanoparticle cermet films with different Au fractions, it was found that vibration phenomena existed in the spectra of films, and envelope curves also appeared significantly in the spectra. The subsequent analysis of optical property of the films would thus be in difficulty. Both qualitative and quantitative investigations showed that these two phenomena were resulted from multiple-beam interference of transmission light beams. Corresponding solution to the problem is given.
