In this popular science experiment,the non-toxic ZnGa2O4:Bi3+fluorescent material was prepared which has three mode luminescence properties including tunable multicolor emission,dynamic photochromic and thermochromic fluorescence properties.By utilizing the"chameleon-like"fluorescence characteristics of the material,we designed three kinds of display schemes for information security application.The experiment is not only interactive and interesting,but also has a good effect on popular science practice,which is helpful to stimulate students'enthusiasm for learning chemistry,and help adolescents experience the rich connotation of"beautiful chemistry".
