Abstract
Ordered photonic structures (photonic crystals) have seen increasing
interest in recent years due to their potential applications, which
depend on fabrication technologies suitable for mass production. In
this paper, we studied by light diffraction the order in photonic
colloidal suspensions composed by core-shell (TiO2@Silica) nanoparticles suspended in ethanol
and water solutions. Light diffraction measurements show order in
these photonic colloidal suspensions, being stronger in ethanol
compared with suspensions in water. Strong and long-range Coulomb
interaction explains the order and correlation in the scatterers’ (TiO2@Silica) position, which favors significantly
the interferential processes as localization of light.
