T he SiO2 spheres w ere then orderl arranged b a centrifugal settling method to obtain the SiO2 photonic cr stals with opal structure. This method is suitable for preparing SiO2 photonic cr stals w ith large size. Using the SiO2 photonic cr stals as templates, Sb2S3 photonic cr stals w ith an inverse opal structure were produced b filling the pores w ith Sb2S3 and then removing the SiO2 colloidal templates w ith h drofluoric acid. Key words: photonic cr stal; inverse opal structure; antimon trisulfide; colloidal template , [7- 9] , . . ,
