Embodiment 1

[0057] In the solvent ethanol, the ratio (molar ratio) of the amount of substances added successively is benzoylacetone, triethylamine, phenanthroline and rare earth chloride EuCl of 3:3:1:1 3 , after reacting at 50-70°C for 0.5 hours, filter, wash, and dry to obtain a kind of rare earth organic complex light conversion agent. The light-changing agent is dissolved in methylene chloride, mixed with a tetrahydrofuran solution of polyvinyl chloride (wherein the weight of polyvinyl chloride is 1000 times the weight of the light-changing agent; the weight of the dispersion medium is 10 times the weight of polyvinyl chloride), Stir well, pour into a mold, and vacuum-dry until transparent to obtain a film that emits high-intensity blue-red dual light.

Embodiment 2

[0059] Add benzoylacetone, ammonia, triphenylphosphine oxide, and rare earth chloride EuCl in the solvent methanol in a ratio of 3:3:1:1:0.05. 3 and LaCl 3 , after reacting at 20-60°C for 2 hours, filter, wash, and dry to obtain a kind of rare earth organic complex light-changing agent. Dissolve the light-changing agent in dimethyl sulfoxide, mix it with the tetrahydrofuran solution of polyvinyl chloride (wherein the weight of polyvinyl chloride is 200 times the weight of the light-changing agent; the weight of the dispersion medium is the same as that of polyvinyl chloride), fully Stir, pour into a mold, and vacuum-dry until transparent to obtain a high-intensity blue-red double-light emitting film.

Embodiment 3

[0061] Add acetylsalicylic acid, triethylamine, triphenylphosphine oxide, and rare earth chloride SmCl in the solvent methanol in a ratio of 3:3:1:1 3 , after reacting at 20-60°C for 3 hours, filter, wash, and dry to obtain a kind of rare earth organic complex light-changing agent. Dissolve the light-changing agent in acetone, mix it with the tetrahydrofuran solution of polyvinyl chloride (wherein the weight of polyvinyl chloride is 500 times the weight of the light-changing agent; the weight of the dispersion medium is 5 times the weight of polyvinyl chloride), and fully stir , poured into a mold, and vacuum-dried until transparent, that is, a film that emits high-intensity blue-red dual light.

Abstract

The light transferring agent of bionic organic RE complex has the general expression of Re1Re2(X)3Y, where, the RE element Re1 is Eu(III) or Sm(III), the RE element Re2 is Gd(III) or La(III), the first ligand X is acetyl salicylic acid or benzoyl acetone, and the second ligand Y is o-phenanthroline or triphenyl oxyphosphine. The light transferring farm plastic film containing the light transferring agent consists of the light transferring agent 0.1-0.5 weight portions, polyvinyl chloride 100 weight portions, dispersing medium 100-1000 weight portions and assistant 0-10 weight portions. The present invention can absorb ultraviolet light and emit blue light favorable to the growth of plant vegetative organ and red light favorable to the reproductive growth of plant, so as to increase yield of crop and improve quality of crop. The present invention has simple production process and is easy for industrial production.

Description

technical field [0001] The invention relates to an ecologically imitative rare-earth organic complex light-converting agent that basically meets the requirements of plant ecological photosynthetic radiation and strong blue-violet light (380-580nm) and red-orange light (580-700nm) The preparation method of the agent; the present invention also relates to an agricultural light conversion film containing the light conversion agent and a preparation method of the agricultural light conversion film. Background technique [0002] With the continuous deepening of my country's agricultural revolution, the development of agricultural light conversion film has attracted people's attention. The research on this technology has been listed as the "Spark Plan" project and the "Tenth Five-Year" Science and Technology Project" project by the Ministry of Science and Technology and the State Bureau of Light Industry. The mechanism of high-efficiency light energy conversion in photosynthesis a...
