  1. Crystal thickness and sphere dispersion dependence of the photonic band gap of silica colloidal crystals

  2. 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
