采用液相渗透(LPI)法制备了掺Eu(III)离子的氧化锆(ZrO2：Eu3+)渗透SnO2反蛋白石复合材料。对掺入的SnO2反蛋白石的绝对反射光谱测量表明，SnO2反蛋白石具有三维有序结构的光子阻带。由于平均折射率的增加，掺入的SnO2反蛋白石的光子阻挡带比SnO2反蛋白石移动了更长的波长。掺入ZrO2：Eu3+的SnO2反蛋白石薄膜比无三维有序结构的薄膜具有更强的发射强度。
Composite materials with europium (III) ion-doped zirconia (ZrO2:Eu3+) infiltrated SnO2 inverse opal have been prepared by the liquid phase infiltration (LPI) process. The absolute reflectance spectra measurement for ZrO2:Eu3+ infiltrated SnO2 inverse opal showed photonic stop band due to three-dimensionally (3D) ordered structure. Photonic stop band of ZrO2:Eu3+ infiltrated SnO2 inverse opals was shifted to longer wavelength compared with SnO2 inverse opals due to the increase of average refractive index. The ZrO2:Eu3+ infiltrated SnO2 inverse opal showed stronger emission intensity than ZrO2:Eu3+ thin film without 3D ordered structure.
