This is the schematic illustration of photonic crystal enhanced chemiluminescence intensity of the oxalate ester peroxide chemiluminescence system. The emission light is inhibited inside the photonic crystal and significantly enhanced at the surface owing to its Bragg scattering. When the stopband of the photonic crystal is matched with themaximum emission wavelength, the chemiluminescence intensity could be enhanced 44.9 times.
