| 摘 要： | 用改进St ber法制备出单分散的SiO2胶球.通过离心沉降法将SiO2胶球有序排列,得到蛋白石结构的SiO2光子晶体,该方法可制备出较大尺寸的蛋白石结构光子晶体.以得到的SiO2光子晶体为模板,通过化学反应向模板间隙填入Sb2S3后再经氢氟酸腐蚀去除二氧化硅胶晶模板,制备出反蛋白石结构硫化锑光子晶体.

| Abstract: | Monodispersed SiO2 spheres were successfully prepared by an improved Sto¨ber method. The SiO2 spheres were then orderly arranged by a centrifugal settling method to obtain the SiO2 photonic crystals with opal structure. This method is suitable for preparing SiO2 photonic crystals with large size. Using the SiO2 photonic crystals as templates, Sb2S3 photonic crystals with an inverse opal structure were produced by filling the pores with Sb2S3 and then removing the SiO2 colloidal templates with hydrofluoric acid. |
