We investigate the effects of photonic crystal structures on radiation imaging properties of a ZnO:Ga image converter. The results show that photonic crystal structures can regulate luminescence distribution and spatial resolving power, which is caused by the light extraction and the defect scattering of photonic crystal structures. The present investigation confirms that photonic crystals can improve the imaging properties of existing image converters and proposes a new coupling mode between the photonic crystal image converter and back-end optical devices, which is beneficial to the application of photonic crystals in the field of radiation imaging.
