| 摘 要： | 以ZnSO4·7H2O和K3PO4·3H2O为原料采用固相反应合成磷酸锌钾,应用均匀设计和数据挖掘技术设计实验方案,采用XRD、SEM和EDS等方法对产物进行表征,并对产物的长余辉发光性能进行了研究。结果表明,根据产物的产率和锌的含量进行回归分析可以建立2个数学模型,对模型进行优化处理可以得到固相法合成磷酸锌钾的最优工艺条件。在n(K3PO4·3H2O)∶n(ZnSO4·7H2O)=1.01、研磨时间31 min、保温温度750℃、保温时间3.2 h的最优条件下制备的KZnPO4纳米片,在紫外光照后可产生蓝绿色长余辉发光,最强发光峰的波长范围为415～530 nm。 |

| Abstract: | 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. |
