摘要/Abstract

摘要： 采用高温固相反应法，在1 100 ℃下制备了Sr₂CaMoO₆红外辐射材料，通过掺杂不同含量的Eu2+离子合成样品.利用X射线衍射(XRD)、红外光谱（IR）、拉曼光谱和红外辐射测试等方法测试了样品的结构与红外辐射性能，研究了体系中不同含量的Eu²⁺离子对样品红外发射率的性能影响.结果表明：随着Eu²⁺离子浓度的增加，样品的XRD、红外光谱、拉曼光谱和红外发射率均发生变化，且Eu²⁺离子在双钙钛矿结构中是以取代Sr²⁺格位而存在于晶格中的.当体系中Eu²⁺含量为5%时,样品红外发射率达到最大值，此时，3～5 μm，8～14 μm和1～22 μm波段的平均发射率分别为0.886,0.936和0.915.

Abstract: The Eu²⁺ doped Sr₂CaMoO₆ powders with high emissivity were fabricated by the traditional solid state reaction at the temperature of 1 100 ℃. The X-ray powder diffraction (XRD), infrared transmittance spectra (IR), Raman spectra and Infrared emission properties were examined to study the structure and the infrared emission properties of the samples. Also the effects of the different amount of Eu²⁺ on the infrared emissivity were investigated. It was found that the XRD patterns, infrared transmittance spectra, Raman spectra and infrared emissivity would change according to the increase of the amount of Eu²⁺,and the Eu²⁺ ions replace the Sr²⁺ site in the structure. When the content of Eu²⁺ is about 5%, the powders reach the highest emissivity with 0.886 at the range of 3~5 μm , 0.936 at the range of 8~14 μm and 0.915 at 1~22 μm.
