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 ...

Design and realization of transparent solar modules based on luminescent solar concentrators integrating nanostructured photonic crystals
(John Wiley & Sons, 2015)
Herein, we present a prototype of a photovoltaic module that combines a luminescent solar concentrator integrating one-dimensional photonic crystals and in-plane CuInGaSe2 (CIGS) solar cells. Highly uniform and wide-area ...

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. ...

Tailor-made directional emission in nanoimprinted plasmonic-based light-emitting devices
(Royal Society of Chemistry (Great Britain), 2014)
We demonstrate an enhanced and tailor-made directional emission of light-emitting devices using nanoimprinted hexagonal arrays of aluminum nanoparticles. Fourier microscopy reveals that the luminescence of the device is ...
