Description
Technical field
The present invention relates to double-function light conversion agent and preparation method thereof.
Background technology
So far, a large amount of research experiments proves, be irradiated in the spectrum of earth surface, and the light of the different wave length of not all is all favourable to plant-growth, really be conducive to the You Lianggefeng district of photosynthesis of plant: (1) blue light region (400 ~ 500nm), the strongest absorption peak of its Determination of Chlorophyll α is 425nm, chlorophyll β, and xenthophylls and the strongest absorption peak of alpha-carotene are 440nm; (2) blood orange district (600-680nm), wherein 645nm is the strongest absorption peak of chlorophyll β, and 660nm is the strongest absorption peak of chlorophyll α.By increasing the blue light of plant or red light irradiation degree, crop root can be made flourishing, and cauline leaf is luxuriant, increasing both production and income and quality superior.
But can for the manufacture of turning light master batch, and canopy membrane interaction can be produced in the most important material light-converting agent of crop growth, although have made some progress, but focus mostly in monochromatic light-converting agent, such as ruddiness light-converting agent mainly rare earth compounding light-converting agent, also there is a lot of problems in the research of this type of light-converting agent: (1) fluorescence lifetime short so far.Seldom there is document can report the fluorescence lifetime of organic coordination compound light-converting agent, even if report also only has effect in 3 months, for the production of turning light master batch, prepare light-converting film, at the button canopy initial stage, light conversion properties can be relatively good, but its light transition function very fast can decline very soon, cause it can not be synchronous with the life-span of film.(2) light function singleness.In the light-converting agent of rare earth organic complex, the ultraviolet of only having that can be used for light-converting film at present turns red function, seldom has the blue light reported and can be converted to needed for photosynthesis of plant.In addition, on light-use, can only UV-light be absorbed, and can not absorb green glow, reduce the utilising efficiency to daylight.(3) expensive.The price of its costliness, hinders its application on light-converting film; In addition, seldom see the report about blue light conversion agent, existing bibliographical information can by the green glow in sunlight and UV-light conversion position blue light and blood orange light, but the not easily compatible practical application of problem to light-converting agent of light-converting agent and polymer has manufactured a difficult problem.
