Abstract

Self-assembled monodisperse nanospheres within microtubes have been fabricated andcharacterized. In comparison with colloidal crystals formed on planar substrates, colloidalnanocrystals self-assembled in microtubes demonstrate high spatial symmetry in theiroptical transmission and reflection properties. The dynamic self-assembly process insidemicrotubes is investigated by combining temporal- and spatial-spectrophotometricmeasurements. The understanding of this process is achieved through both experimentallyrecorded reflection spectra and finite difference time domain (FDTD)-based simulationresults.
