Over a decade ago, theorists predicted that photonic crystals active at visible and near-
infrared wavelengths would possess a variety of exciting optical properties. Only in the last …

The synthesis and applications of organic-inorganic nanostructured colloids and colloidal-
based materials are reviewed here. Emphasis is placed on the strategies and synthetic …

Whereas considerable interest exists in self-assembly of well-ordered, porous “inverse opal”
structures for optical, electronic, and (bio) chemical applications, uncontrolled defect …

The properties of nanoparticle aerosols of size ranging from 4.9 nm to 13 nm, generated by
laser ablation of solid surfaces are described. The experimental system consisted of a …

Compact inverse‐opal structures are constructed using non‐aggregated TiO2 nanoparticles
in a three‐dimensional colloidal array template as the photoelectrode of a dye‐sensitized …

Nanostructured tungsten oxide (WO3) thin films have been prepared by the sol–gel method
following the inorganic route in which alcoholic solutions containing tungsten salts have …

Naturally occurring gem opals would seem to be the inspiration for the recent explosion of
work on three‐dimensionally ordered macroporous, or “3DOM” materials. Myriad techniques …

Striking color changes in the visible spectrumare produced when the voids of three‐
dimensionally ordered macroporous (3DOM) silica, alumina, and zirconia (“inverse opals”) …

The emerging fields of nanoscience and nanoengineering are leading to unprecedented
understanding and control over the fundamental building blocks of all physical matter …

The synthesis and characterization of nanostructured heterojunction solar cells based on
inverse opal titanium dioxide (TiO2) films is discussed. Photonic films with thicknesses of 0.9 …
