摘　　要：理论上研究了吸收层材料的光学常数,该常数满足从紫外线到近红外波长范围的四层结构的光子-热转换的高效率。通过使用有效介质近似(EMA)模型,复合材料(金属陶瓷)的光学性能与模拟材料的光学性能非常吻合。此外,提出了使用Ti-MgF2金属陶瓷作为吸收层的具有高光子-热转换效率的四层膜结构,其在300~1600 nm的波长范围内具有约95.1%的高吸收率。研究结果为实现高效率的光热转换器件提供了新途径,显示了优良的应用前景。The optical constants for the absorbing layer material,satisfying high efficiency of the photon-to-heat conversion of a four-layer structure from ultraviolet to near-infrared wavelength range,are theoretically studied.By employing the effective medium approximation(EMA)model,the measured optical properties of the compos⁃ite materials(cermet)show in great agreement with that of the simulated ones.Furthermore,a four-layer film structure with high photon-to-heat conversion efficiency using Ti-MgF2 cermet as the absorption layer is proposed to have a high absorptance of about 95.1%achieved in the wavelength range of 300~1600 nm.The research results provide a new method to realize high-efficiency photon-to-heat conversion devices and show excellent appli⁃cation prospects.
