Abstract: | Silica inverse opal photonic crystals (PCs) were fabricated by using a sacrificial polymer template method, and were characterized
by scanning electron microscopy and reflection spectra. The fluorescence of tricolor fluorescent powders has been enhanced
obviously by silica inverse opals as the emission wavelengths of the tricolor fluorescent powders are in the range of stop
bands of the inverse opal PCs, which demonstrates that the PCs will be efficient and selective reflection mirrors. A promising
application of the strategy would be in novel effective lighting devices.
