采用高温固相反应法，在1100℃下制备了Sr2 CaMoO6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，3～5μm，8～14μm和1～22μm波段的平均发射率分别为0.886，0.936和0.915．

The Eu2 +doped Sr2 CaMoO6 powders with high emissivity were fabricated by the traditional sol-id state reaction at the temperature of 1 100℃.The X-ray powder diffraction ( XRD) , infrared transmit-tance 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 spec-tra, 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 3~5μm , 0.936 at the range of 8~14 μm and 0.915 at 1~22 μm.
