Abstract: | The photonic band gap of SBA-15 ordered mesoporous structure is investigated when used as photonic crystals. The filling fraction has more significant effects on the width and attenuation length of PBG than does the dielectric contrast, whereas the PBG position is strongly dependent on both the filling fraction and dielectric contrast. Since the position of PBG occurs between 30–40 nm and the width is about 4–5 nm, SBA-15 with such a narrow gap is expected to be applied as filters in soft X-ray spectrum. |
