摘要：
Polystyrene artificial opals have been grown by slow gravity sedimentation from aqueous suspension of morrodisperse nano-spheres of different diameters. These opals have been infiltrated with diacetylenic monomers, which have been subsequently polymerized. The morphology of the surface has been characterized by atomic force and scanning electron microscopies. In addition, a careful micro-optical characterization of these samples has been performed. The photonic band structure of the opals was derived from variable-angle micro-reflectance measurements and favorably compared with that theoretically calculated. (C) 2003 Elsevier Science B.V.
