Colloidal assemblies consisting of monotonic polystyrene microspheres with a controlled degree of ordering were fabricated, and exhibited rich spectral behaviors. Smooth and spike-modulated broad attenuation regions in transmission spectra were observed in highly disordered and partly disordered samples, respectively, in contrast to the narrow peaks observed in well-ordered photonic crystals. These properties are interpreted consistently by analyzing the variation of the volume of closely packed units.
