Research on infrared property of Cd1-x ZnxS pigments
【摘要】 采用固相反应方法制备名义组成为Cd1-xZnxS三元系半导体颜料。利用X光衍射表征体系的结构,结果表明,最终实验产物均为纤锌矿结构。测试样品的红外吸收光谱以及3~5μm和8~14μm双波段红外发射率,研究Cd/Zn配比对光谱特性的影响,探讨发射率随波长、配比及温度的变化而改变的机理。
【Abstract】 The semiconductor of Cd1-x ZnxS is synthesized by solid state reaction. The constructions are characterized by XRD.It is demonstrated that the samples obtained through different Cd/Zn ratio are all hexagonal. The infrared spectra and the emissivity of both 3-5 μm and 8-14 μm are tested. The effect of the Cd/Zn ratio on the spectra was studied . The mechanism that the emissivity of Cd1-x ZnxS changes along with the change of wave length, Cd/Zn ratio and temperature was discussed.
