CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishPolystyrene artificial opals have been grown by slow gravity sedimentation from aqueous suspension of monodisperse 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 opalswas derived from variable-angle micro-reflectance measurements and favorably compared with that theoretically calculated.

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 opalswas derived from variable-angle micro-reflectance measurements and favorably compared with that theoretically calculated. | |
