摘　　要：基于3.87μm聚苯乙烯(PS)微球,通过垂直基片自组装法制备了光子禁带位于红外波段的有序三维光子晶体.研究发现,当悬浮液中乙醇和水的比例为2:8(V%)时,微球的排列有序度最高,缺陷最少;随着微球浓度增大,微球堆积层数增多,光子晶体厚度增大.表征了不同有序度的光子晶体在红外波段的反射性能和辐射性能,结果表明微球排列有序度越高,有序面积越大,光子晶体的反射率越高,辐射率越低,从而有效抑制目标表面的红外辐射.The ordered three-dimensional photonic crystals with infrared photonic band gap was prepared from 3. 87 μm polystyrene（ PS） microspheres by vertical substrate self-assembly method. It is found that the microspheres exhibit the highest order and least defect when the ratio of ethanol to water in the suspension is 2：8（ V%）. Increasing the concentration of microspheres in the suspension,the number of stacking layers and the thickness of the photonic crystals were improved. Then the reflection and radiation properties of the photonic crystals with different ordering degree in the infrared band were characterized.The results reveal that higher ordering degree and larger ordered area of the microspheres lead to higher reflectivity and lower emissivity of the photonic crystals,thereby effectively inhibiting the infrared radiation of the aim surface.
