The Application of Lights-Conversed Polyethylene Film for Agriculture

摘要

Lanthanum|rhodamine (6G and B) complexes were synthesized by Rheological Phase Reaction Method. Lanthanum|rhodamine (6G and B) complexes doped polyethylene films which have a function of lights|conversion were prepared. The emission and excitation spectra were measured. The experiments of growing seedling and culture were carried out in the shed built with doped and undoped polyethylene films. Lanthanum|rhodamine doped polyethylene films which have a function of lights|conversion can efficiently convert the green light in the sunlight to the red light for photosynthesis of crops, to promote the maturing of crops and raise the yield of crops.
