Zinc oxide nanorods are used to emit light in the UV region because of their high energy band gap. In this paper, a set of ZnO nanorods is used to design a random laser in the UV spectrum region and Anderson's Localization in the environment includes these nanorods, is investigated then is modeled. The proposed model for the investigation of ZnO nanorods is twodimensional. The role of nanorods is to create scatter and diffraction and thus produce local cavities to create coherent random laser spectra. Their other role is stimulated emission and laser because of the good optical gain. The random laser modes produced along with the laser gain are evaluated..
