Abstract
Colloidal crystals are grown in capillaries. Experimental results demonstrate that these colloidal crystals are formed in a structure with cylindrical symmetry. The colloidal crystals are relatively stable. In all radial directions in the plan perpendicular to the axis of the capillary, the transmission spectra are the same and the wavelength of the band gaps are the longest. In other directions, the wavelength of the band gap is gradually blue shifted as the angle between light and axis of capillary decreases. This axial symmetry of band gap will have many potential applications.
