In this work, we investigate the photonic stop band of multilayers, which is the simplest possible 1D photonic crystal, using MIT electromagnetic equation propagation software. The transmission spectra were simulated, and the effect of the number of layers and the contrast in the dielectric constant on the photonic band gap was studied. The ZnO/SiO2 multilayer was fabricated using radio frequency magnetron sputtering. The refractive indices of ZnO and SiO2 were found from the absorption spectra. The transmission spectra of the photonic crystals with eleven layers were studied using a UV–visible spectrophotometer. A dip in the transmission spectra in the wavelength range of blue was observed. The experimental result matched the simulated transmission spectra. The cross-sectional view of the multilayers was observed using a field emission scanning electron microscope.
