摘要Three-dimensionally ordered macroporous (3DOM) ZrO2:Eu3+ inverse opal materials prepared by polystyrene (PS) colloidal crystal templating, using the sol-gel method, were successfully fabricated. Their crystal structure, morphology, and photoluminescence (PL) properties and the effect of the photonic stop-band on the spontaneous emission of Eu3+ ions were studied and compared with those of the nonporous sample. In the 3DOM ZrO2: Eu3+, significant suppression for the 5D(0)-F-7(1) transition peaking at 590 nm was observed, which was in good agreement with the photonic band gap calculated (similar to 586 nm). After grinding the 3D ZrO2:Eu3+ inverse opal material, the suppression of emission was restored due to the disappearance of the photonic band gap. In the 3DOM ZrO2:Eu3+, the luminescent lifetime of D-5(0)-F-7(J) depended strongly on emission wavelengths, which was mainly attributed to the appearance of different Eu3+ centers. In the 3DOM ZrO2:Eu3+, three symmetry sites for Eu3+ were identified by site-selective excitation, differing from the nonporous sample, in which only one site was identified.
