Abstract：Terbium was selected as test material for its strong fluorescence effect, and sulfosalicylic acid was used as first ligand, polyvinyl alcohol and polyethylene glycol 2000 as co-ligand, the fluorescence property of complexes in the two systems of ethanol solution and aqueous solution was explored. It was obtained that the polyvinyl alcohol and polyethylene glycol 2000 are the excellent co-ligands. Further study showed that sufactant is good for fluorescence enhancement of the different complexes and especially sodium dodecyl sulfate is best while exploring the impact of acidity on the fluorescence intensity. Terbium-sulfosalicylic acid-polyvinyl alcohol complex was obtained under the conditions of 342 nm for excitation wavelength, and 545 nm for emission wavelength. Mixing the complex into the plastic film in proper proportion, the authors prepared the rare earth light conversion membrane which allowed ultraviolet portion of sunlight to convert to green light the crop photosythesis needed to effectively improve the photosynthetic efficiency.
