Abstract

Zero-dimensional (0D) and one-dimensional (1D) nanomaterials can be coarrayed in a cocontinuous manner using convective force driven self-assembly to obtain hybrid nanomaterials. The process is demonstrated using 0D polystyrene colloids and 1D Au nanorods. The flexural properties of the spherical colloidal templates and the concentration of the nanosized building-blocks are crucial parameters that determine the dominant rod-colloid hybrid nanoarrays that are obtained. Plasmon resonance phenomena in the resulting hybrid systems are examined by ultraviolet-visible transmission/absorbance spectroscopy. The resulting coarrayed nanostructures show variable optical stop bands dependent on the angle of the incident light relative to the plane of the coarrayed film.
