Rare earth ion is distinctive outer electronic structure, make its are being formed organic or after the inorganic compound, absorb the excitation of close ultraviolet light easily, blast off consequently go out to see fluorescence ionicly blast off at the center accordingly. Rare homemade switchs optical thin coating, it is to use organic distribute system to ultraviolet light tall absorb, the tall glow efficiency of rare earth ion, and rare earth organic cooperate content to arrive dispersedly those who have is muti_function be developed in farming film and become, those who have function of fluorescent changeover glow is agricultural high polymer material. Rare homemade switchs optical thin coating is OK the blood orange that is the majority change that adverse ultraviolet light grows to crop in sun's rays plant photosynthesis to be able to be used directly is smooth, through improving the illumination quality of crop, raise the chlorophyll content inside crop body then. Accordingly, compare with common film photograph, the can apparent photosynthesis strength that increases crop, raise ground temperature and canopy content of salt of lukewarm, the nitric acid in reducing crop illness index and fructification, accelerate birth process, raise products to measure 7% ～ 48% , C of the vitamin in increasing fructification, .

China already made the world's biggest farming film market at present, according to statistic of national statistic branch, our country needs every year to use many tons of 100 farming film about, its middle peasant uses ground film average year dosage already exceeded 300 thousand tons. Forecast according to concerning a section, to 2002 the usable floor area of film of our country farming already of gross of area of Cong Zhangeng ground 4.7% rise 6% . Because a lot of areas of our country will adjust agriculture cultivate a structure substantially, economy kind crop cultivates an area to increase, grain crop large area decreases, and most economy kind crop needs by farming film grow seedlings, muti_function farming film is compared before hopeful grows 20% to control, common film demand will drop 15% the left and right sides, among them muti_function the applied scale of conservatory canopy film will raise 30% above. Rare homemade switchs optical thin coating is to be in muti_function over the foundation of farming film, increased to turn again smooth function, can apply at agriculture widely, development potential is tremendous.

Turn glossy material learns to reach other hi-tech domain to also have wide development perspective in industry, medicine. In the sky follow an earth ozonosphere gradually rare, antarctic in the sky ozone is empty expand gradually, people is deeply concerned increasingly to ultraviolet radiate. Turn optical technology applies in fiber of glass, sunshine board, spin, can be absorbed effectively and change the ultraviolet ray in sunlight, improve illumination condition, reduce ultraviolet radiate. In addition, rare homemade switchs glossy material still can be used in fluorescence of macromolecule of chemical analysis, indication parts of an apparatus, rare autochthonal thing the respect such as the fluorescent mark of bougie and element of rare earth live thing. Accordingly, rare homemade switchs glossy material has vast market potential and enormous socioeconomy beneficial result.
