Abstract

Experimental results demonstrate that the band gap of colloidal suspension crystal changes with both the thickness of crystal and the dispersity of micro-spheres. As the thickness decreases, a red shift of band gap is observed, and there is a maximum of red shift. The values of the maximum red shifts are dependent on the standard deviations of micro-spheres. The experimental results are consistent with theoretical calculation. As the colloidal suspension crystal is assembled from micro-spheres with a standard deviation of 8.4% in a thick cell, an incident angles independent broadband is observed, which is explained as an amorphous structure. Two amorphous models are discussed.
