| 摘 要： | Mn-Co-Ni-O作为一种重要的热探测材料被广泛应用于各类领域。作者使用研磨和烧结的方法制备了NiMn2O4和Mn1.56Co0.96Ni0.48O4块体材料。通过X射线衍射实验研究了两种块体的结晶情况,发现半径较大的Co阳离子的加入会导致块体结晶性变差。通过椭圆偏振光谱测试分别获得了NiMn2O4和Mn1.56Co0.96Ni0.48O4在紫外-远红外宽波段的光学常数和介电常数,发现添加离子后二者光学性质(光学常数的强度和峰位)具有一定区别。利用傅里叶光谱仪得到了两种材料的反射光谱,并与用光学常数计算出的数值进行了比较,最后评估了表面粗糙度对反射谱的影响。

| Abstract: | As an important thermal detection material, Mn-Co-Ni-O has been widely used in variety of fields as the key thermal detector. NiMn2O4 and Mn1.56Co0.96Ni0.48O4 bulk materials were prepared by grinding and wintering methods. The crystallization of the two blocks was studied by X-ray diffraction experiments, and it was found that the addition of Co cation with larger radii resulted in deterioration of the bulk crystalline. The optical constants and dielectric constants of NiMn2O4 and Mn1.56Co0.96Ni0.48O4 in the ultraviolet-far infrared wide band were obtained by ellipsometry. It was found that significant difference appeared between the optical properties (intensity and peak position of optical constants) of the two materials after the addition of ions. The reflectance spectra of the two materials were obtained by Fourier spectrometer, it was compared with the calculated values of optical constants, so the effect of surface roughness on reflection spectra was evaluated. |
