For take fully advantage of solar energy, the blue light conversion agent Ca 0.6 Sr 0.4 F 2 :Eu 2+ ,Sm 3+ and red CaS:Eu were prepared in this paper. X-ray power diffraction (XRD) analysisconfirmed phase formationof these agents.The luminescence intensity influencedby theconcentration rare-earth-doped was discussed.Measuring results revealed thatthe agents canabsorb 375nm, 570nm radiations emit 435nm, 640nmlight, respectively.The emitting spectra them are matchedwith absorption spectrum chlorophyll. Light film by introducing into polyethylene (PE). The trials vegetables plantingin greenhouses that covered filmsindicate thatconversion films able to enhance availability accelerate ripening vegetables, increase yield higher than 19.8%.
