Abstract

Inverse polyvinylidene fluoride (PVDF) opals with a temperature tunable photonic band gap (PBG) were fabricated by the sol–gel process using SiO2 opal templates. The samples exhibited an olivine to dark blue color after heat treatment at different temperatures. Their microregion reflection spectra showed that the inverse PVDF opal PBG blue-shifted from 573 nm to 498 nm when the treating temperature increased from 80 °C to 160 °C. This was due to a reduction of the inverse PVDF opal periodical size during the heat treatment process. Such inverse PVDF opals with temperature tunable PBGs have a great potential in device applications.
