• Manipulation of the photoluminescence spectra of light-emitting materials doped in three-dimensional (3D) inverse opal photonic crystals is investigated. Quinacrine dihydrochloride molecules doped highly ordered SiO sub(2) inverse opal is successfully synthesized by co-assembly combined with double-substrate vertical infiltrate method. The quinacrine dihydrochloride-doped and -undoped SiO sub(2) inverse opals each exhibit an apparent photonic band gap (PBG) in the visible light region. Significant suppression of the emission is observed when the PBG is overlapped with the quinacrine dihydrochloride emission bands. The mechanism of suppression effect of PBG in inverse opal on the fluorescence intensity of quinacrine dihydrochloride molecules is studied.
