Experimental Research on Characteristics of Long-Wave Infrared Material Pb1-xGexTe

After detailed experimental research on characteristics of long-wave infrared material Pb1-xGexTe we find the effect on optical constants(n,K) at different substrate temperatures and ambient temperatures using Pb1-XGeXTe,which is that density of layer membrane becomes higher and affects on its transmission along with substrate temperature increasing as well as film refractive index and absorptivity. Pb1-XGeXTe film refractive index decreases with the wavelength increasing and its decreasing magnitude changes with ambient temperature.The experimental results show that the experimental research on characteristics of long-wave infrared material Pb1-XGeXTe makes theory and practice unified.The preparation process and coating process of Pb1-XGeXTe constantly improving promot the performance of airspace optical remote sensing instruments.
