Description We present a systematic analysis of three dimensionally ordered photonic crystals made of dyed-polystyrene spheres fabricated using the newly reported inward growing self assembling method. The SEM and AFM images show good ordering of the spheres with (111) plane parallel to the substrate. The photonic stop band is tuned by varying the angle of incidence of light and made to coincide with the emission wavelength of the dyes. The multiple Bragg diffraction effects observed at high angles of incidence are interpreted. The high reflectance values obtained along with the observation of the higher order bands, and the photonic stop band splitting at high angles of incidence show the superior quality of the photonic crystals fabricated using these dyed polystyrene spheres in less than three hours.
