ZnO:Tm,Gd materials with high quality blue light-emitting were successfully prepared using the chemical co-precipitation method. The surface morphology, composition, crystal structure and fluorescence properties were investigated using the thermogravimetric analysis/differential thermal analysis (TG/DTA), scanning electronic microscopy (SEM), X-ray diffraction (XRD), and photoluminescence (PL). The results showed that the lowest sintering temperature was 580°C, the optimal sintering temperature was 900°C, ZnO:Tm 3+ , Gd 3+  had two emission peaks:  1  D 2  →  3  H 4  and  1  G 4  →  3  H 6 , the optimal heat preservation time was 3 h, the proportion of matrix and doping elements was 100: 2, and the optimal proportion of Tm and Gd was 3: 2.
