ZnAl2O4:Cr3+, Tb3+ powders with different dopant contents have been synthesized by sol-gel method using the following precursors: zinc nitrate (Zn(NO3)2), aluminum nitrate (Al(NO3)3), terbium nitrate (Tb(NO3)3), chrome nitrate (Cr(NO3)3), and citric acid. The effect of the Cr3+, Tb3+ concentration and heat-treating temperature on structural and optical properties of the synthesized samples has been studied.
