Rare earth doped synthetic opals and inverse opals
(Spie - Int Soc Optical Engineering, 2002-01-01)
Monodisperse spheres of silica and latex were obtained by a surfactant free styrene polimerization and the Stober method respectively. Controlling settling either by centrifugation or by dip-coating colloidal crystals could ...

Optical analysis of the fine crystalline structure of artificial opal films
(American Chemical Society, 2009-12)
Herein, we present a detailed analysis of the structure of artificial opal films. We demonstrate that, rather than the generally assumed face centered cubic lattice of spheres, opal films are better approximated by ...

Analysis of artificial opals by scanning near field optical microscopy
(American Institute of Physics, 2011-04)
Herein we present a detailed analysis of the optical response of artificial opal films realized employing a near-field scanning optical microscope in collection and transmission modes. Near-field patterns measured at the ...
