报道了用真空蒸发法制备的 Ｃｕ － Ｍｇ Ｆ２ 金属陶瓷薄膜的微结构与光学特性的测试结果。在２２０ ｎ ｍ ～８００ ｎ ｍ 波段，薄膜的反射率很低，仅为１ ％ ～２ ．５ ％ ；透射率则在２００ ｎ ｍ ～６５０ ｎ ｍ之间随波长增大近似呈抛物线上升，至６５０ ｎ ｍ 处达到最大值４６ ％ ；吸光度随波长增大呈指数下降，在４００ ｃｍ － １ ～４ ０００ ｃ ｍ － １ 红外波段，薄膜的吸收率较高，约６５ ％ 。研究结果表明， Ｃｕ － Ｍｇ Ｆ２ 金属陶瓷薄膜可用于紫外—红外光区的减反射膜层以及太阳能转换器件的膜层。
The test results of the microstructure and optical properties of Cu - Mg F2 cermet films prepared by vacuum evaporation were reported. In the 220 nm ~ 800 nm band, the reflectance of the film is very low, only 1% ~ 2. 5%, while the transmittance increased from 200 nm to 650 nm with a parabolic curve increasing to a maximum of 46% at 650 nm. The absorbance decreased exponentially with increasing wavelength, ~ 4 000 c m - 1 infrared band, the absorption rate of the film is high, about 65%. The results show that the Cu - Mg F2 cermet thin film can be used in the antireflection coating of UV - IR and the film of solar energy conversion device.
