In this paper, we present one method to determine the band gap energy of ZnO and ZnO:Tb3 materials. ZnO:Tb3 material has prepared by forced hydrolysis method. All samples have zinc oxide hexagonal wurzite structure. The obtained results show that the energy of the band gap depends on Tb3 molar ratio.
