基于Ti-MgF2金属陶瓷的高效率四层光热转换薄膜的研究
The study of high-efficiency four-layer photon-to-heat conversion film based on Ti-MgF2 cermet
摘要
Abstract
The optical constants for the absorbing layer material,satisfying high efficiency of the photon-to-heatconversion 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 re?sults provide a new method to realize high-efficiency photon-to-heat conversion devices and show excellent appli?cation prospects.关键词
