Abstract: This paper discusses two synthesis methods for dual organic ligands rare-earth light conversion agent, one is Solid phase synthesis method, and another is liquid phase synthesis method. By contrast of infrared spectra, dispersion properties in aqueous solution and Anti-UV effect of each light conversion agent made by both methods, we find that in liquid phase synthesis, europium ionic binding with organic ligands more fully, and the conversion agent made by liquid phase synthesis is easily solved and dispersed uniform, and its anti-UV effect is better than that made by solid phase synthesis methods.

Key words: light conversion agent, solid phase synthesis, liquid phade synthesis, UV&ndash, protection
