含[Eu(hfa)3(TPPO)2]的紫外转红光聚乙烯膜的制备、表征及性能研究
Preparation,Characterization and Properties of[Eu(hfa)3(TPPO)2]Containing Polyethylene Films Capable of Converting UV Light to Red Light
摘要
Abstract
A linear low density polyethylene(LLDPE)light conversion film containing different concentrations of the light conversion agent[Eu(hfa)3(TPPO)2]was prepared,and its performance was evaluated.The scanning electron microscopy(SEM)results show that the surface of the polyethylene film containing[Eu(hfa)3(TPPO)2]is smooth,with no particle aggregation.The fluorescence spectra show that the light conversion film is excited in the ultraviolet region(200～345 nm)and exhibits strong emission in the red region(600～700 nm),matching the absorption range of chlorophyll.The result suggests that the light conversion film can absorb harmful ultraviolet light from sunlight for plant growth and convert it into the red light needed for plant growth,effectively achieving light quality regulation.The light conversion film containing 1.0%[Eu(hfa)3(TPPO)2]demonstrates the highest fluorescence quantum yield(66.38%).Under the natural light,the photosynthetic photon flux density(PPFD)transmitted through the light conversion film increases in the red region,indicating excellent light conversion performance.Ultraviolet-visible transmission spectra reveals a slight decrease in transparency compared to pure LLDPE film,indicating good light transmittance of the light conversion film.关键词
