Abstract: In this paper, the light curing resin was prepared by blending rare earth light conversion agent with sulfhydryl and double bond monomers. Two kinds of agricultural light conversion films were prepared by sulfhydryl-double bond or double bond-double bond click reaction. The structure and properties of the films were characterized by fluorescence spectrum, UV spectrum, SEM and tensile propertytest. The results show that the UV light at 353 nm can be converted into red light at 613 nm and 617 nm by using light conversion film which have been prepared by adding 0.5% rare earth light conversion into light curing resin, sulfhydryl-double bond click reaction. The film has good light transmittance and light conversion performance, and mechanical properties with tensile strength of 12.72 MPa, which has good application in agricultural greenhouses, glass greenhouses and other aspects.
