Description

Upper conversion light conversion agent and preparation method thereof and the agricultural conversion film of upper conversion and its preparation Method
Technical field
The invention belongs to light conversion agent and conversion film field, turns agricultural more particularly to upper conversion light conversion agent and upper conversion and turns light Film and preparation method thereof.
Background technology
Light and temperature are the important ecological factors of growth and development of plants, have great shadow to the morphogenesis and growth of plant Ring, especially light quality composition plays regulating and controlling effect with growth of the ratio to plant, pigment composition, photosynthesis and metabolism.Perhaps More researchs show that the development light regulation and control of plant growth and leaf pigment, feux rouges is advantageous to assimilate carbohydrate, and blue light is favourable In anabolic protein class material.The physiological responses that different plants change to spectral component are also different, and dicotyledon compares unifacial leaf Plant changes more sensitive to spectral component.Scientific investigations showed that the absorption spectrum of chlorophyll is 400nm~480nm blue violet light Area and 600nm~680nm blood orange light area, that is to say, that to photosynthesis significantly blue violet light and blood orange light, Qi Taguang Effect and unobvious, it is or even harmful.However, in sunshine received by earth surface, wavelength is 300nm~750nm's Light only about accounts for the half of whole solar spectrum, that is to say, that the light being largely harmful to plant growth in solar spectrum also be present, And it is beneficial to the blue violet light and blood orange luminous intensity deficiency of plant growth, influences the efficiency of photosynthesis of plant.
Conversion film has been applied in plant culture, and different light medium film can carry out regulating plant growth as physical means.According to According to photosynthesis of plant and solar spectrum feature, Development and design goes out to turn ultraviolet light → blue Light Film, green glow → feux rouges film, red indigo plant is answered Close bimodal gain film, the rare earth compounding type conversion film for turning ultraviolet light → feux rouges etc..Such conversion film is mainly with single base light conversion agent For light conversion agent, its absorption spectrum is predominantly located at purple light and black light region, has regulation and control light quality and light intensity, will be right in daylight The invalid or poorly efficient purple light of photosynthesis and black light are changed into the efficient blue light of photosynthesis and feux rouges, increase soil temperature Effect.However, it is worth noting that ultraviolet light only accounts for 1~3% in daylight composition, during many sample tests, under uviol lamp Have and significantly turn light effect, but actual button canopy effect unobvious, one of them most important reason is exactly to be changed Purple light and near ultraviolet light source are very little.And substantial amounts of more than 720nm near infrared light is also anti-by plant stem-leaf in solar spectrum composition Penetrate, cause substantial amounts of waste.
The content of the invention
Lighted to overcome above-mentioned light conversion agent in the prior art to carry out lower conversion, i.e., purple light be converted into red blue light, Or the problem of blue green light is converted into feux rouges, of the invention goal of the invention are to provide that a kind of cost is low, luminous efficiency is high Upper conversion light conversion agent and preparation method thereof；Use that cost is low, luminous efficiency it is a further object to provide one kind High upper conversion light conversion agent, improves agricultural conversion film of upper conversion of plant growth rate and preparation method thereof.
To solve above-mentioned the deficiencies in the prior art, the technical solution adopted in the present invention is as follows：Upper conversion light conversion agent, chemistry Forming formula is：NaY2F7:Er, Re, wherein Re represent the one or more in Pr, Sm, Dy, Ho, Tm, Yb rare earth element.
