摘　　要：SiO2 and ZnO inverse structure replicas have been synthesized using butterfly wings as templates. The laser diffraction performance of the SiO2 inverse structure replica was investigated and it was found that the zero-order light spot split into a matrix pattern when the distance between the screen and the sample was increased. This unique diffraction phenomenon is closely related to the structure of the SiO2 inverse structure replica. On the other hand, by analyzing the photoluminescence spectrum of the ZnO replica, optical anisotropy in the ultraviolet band was demonstrated for this material.SiO2 和 ZnO 反的结构复制品作为模板用蝴蝶翅膀被综合了。SiO2 反的结构复制品的激光衍射表演被调查，在屏幕和样品之间的距离什么时候被增加，被发现零顺序的轻点分成了一个矩阵模式。这唯一的衍射现象是仔细与 SiO2 逆的结构有关组织复制品。由分析 ZnO 复制品的光致发光光谱，在另一方面，在紫外乐队的光 anisotropy 为这材料被表明。
