摘要根据单纯材料的光谱特性曲线,分析了其多声子辐射机理,并探讨了以单
纯材料为辐射粉体基料的红外辐射涂料的适用范围及其不足。通过分析杂质对 l ~ 5
波段辐射性能的影响,提出化学掺杂是改善红外短波区辐射性能的有效途径。还根

Synopsis Based on the spectrum curve of simpiicity materiais,its excessive phonons radiant
mechanism is anaiyzed in this paper. The appiicabie scope of infrared radiant coating made from the
simpiicty materiais and its shortages are aiso described. After anaiyzing the effect of impurity on the
,
radiant performance in l to 5!m wave band it can be seen that chemicai aduiteration was an effec-
tive approach to improve the radiant performance. In addition,the existing forms of impurity in sin-
tered materiais is aiso discussed according to the microstructure of transition metai oxides sintered
materiais.
Keywords infrared radiance impurity radiant mechanism phonon free carried current
