【摘要】 以CdS、ZnS等为原料,通过Ar气氛固相反应法分别在700、800、900、1000℃制备了硫化物固溶体颜料,并分别采用X射线衍射仪(XRD)、X射线能谱仪(EDS)、扫描电镜(SEM)对粉体进行结构、成分、形貌表征,通过IR-2型发射率测试仪测试粉体在8- 14μm波段的红外发射率。测试结果表明,热处理温度对粉体的发射率影响明显,随温度升高,发射率下降, 从0．98-0．76不等。此外,本文从晶格畸变角度分析了硫化物半导体颜料的发射率影响机理。更多还原

【Abstract】 Semiconductor sufide pigments were prepared by Ar atmosphere solid phase reaction with CdS,ZnS powders as reagents. The structure, component and the surface morphology of the particles prepared were characterized by X-ray diffraction(XRD), energy dispersive spectra(EDS) and scanning electron microscope(SEM). The infrared emissivity of the pigments during 8-14μm wave band was measured by IR-2 infrared emissometer. The results showed that heat treatment temperature played an important role in the emissivity. The infrared emissivity decreased from 0. 98 to 0. 76, when the heat treatment temperature increased. The influence mechanism of the emissivity was discussed detailedly in the aspect of crystal lattice aberrance.更多还原
