摘 要：In this paper,the fracture surfaces of a light-conversion film were observed using a scanning electron microscope（SEM）,and then,the fluorescence spectra and mechanical properties of the film were tested.The SEM results show that the average diameter of the light conversion agent is 500 nm.The results of the mechanical properties tests show that the tensile strengths of light-conversion film increase from9.86 to 12.16 MPa and that the strain at breakage increases from 2.37% to 2.75%.In addition,the application effects of the light-co nversion film were studied.The results indicate that plant height,length of the maximum leaf,width of the maximum leaf and breadth of the plants increase by 24.43%,15.30%,15.60% and 19.07%,respectively.The quality of Chinese flowering cabbages treated with the lightconversion film is superior,including a 9.09% increase in the soluble protein content,a 21.27% increase in the polyphenol content,and a 19.15% increase in the soluble sugar content.Based on these results,light-conversion films can be applied in agricultural production.
