Potassium zinc phosphate(KZnPO4) was synthesized by solid-state reaction using K3PO4·3H2O and ZnSO4·7H2O as reagents.Experimental project was designed by uniform design and data mining technology.The obtained product was characterized by X-ray diffraction,scanning electron microscope and energy disperses spectroscopy,and its property of long lasting phosphorescence was also studied.Based on the yield and zinc content,two mathematical models were established by regression analysis.The best technology conditions of synthesis can be obtained by optimization of these two models.Under the optimum reaction conditions: molar ratio of n(K3PO4·3H2O)∶n(ZnSO4·7H2O)=1.01,grinding time 31 min,holding temperature 750 ℃,holding time 3.2 h,the prepared product is KZnPO4 with nano-lamellar structure.After ultraviolet radiation,the obtained product show blue-green long lasting phosphorescence and the highest emission peak is located at 415~530 nm.
