Size and shape of supported zirconia nanoparticles determined by x-ray photoelectron spectroscopy
(American Institute of Physics, 2007)
The initial stages of growth of zirconia nanoparticles deposited on SiO2, Y2O3, and CeO2 substrates have been studied by the x-ray photoelectron spectroscopy peak shape analysis. ZrO2 was deposited by plasma decomposition ...

Effect of extinction on the high-energy optical response of photonic crystals
(American Institute of Physics, 2007)
An analysis of the optical response of photonic crystals in the high-order band energy range is herein presented. High and abruptly fluctuating specular reflectance is predicted for perfect lattices at those energies even ...

Physical origin of the high energy optical response of three-dimensional photonic crystals
(Optical Society of America, 2007)
The physical origin of the optical response observed in three-dimensional photonic crystals when the photon wavelength is equal or lower than the lattice parameter still remains unsatisfactorily explained and is the subject ...

Relation between growth dynamics and the spatial distribution of intrinsic defects in self-assembled colloidal crystal films
(American Institute of Physics, 2008)
Herein we establish a clear relation between the parameters that govern the growth dynamics and the structural quality of colloidal crystal films. We report an optical analysis of the spatial distribution of intrinsic ...

Towards a full understanding of the growth dynamics and optical response of self-assembled photonic colloidal crystal films
(Royal Society of Chemistry (Great Britain), 2009)
Recent advances in the comprehension of the growth dynamics of colloidal crystal films opens the door to rational design of experiments aiming at fabricating lattices in which the density of intrinsic defects is minimized. ...
