Abstract

Potassium zinc phosphate (KZnPO

) was synthesized by solid-state reaction using K

·3H

O and ZnSO

·7H

O 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(K

·3H

O):n(ZnSO

·7H

grinding time 31 min

holding temperature 750℃

holding time 3.2 h

the prepared product is KZnPO

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.
