【Abstract】 The rare earth organic light conversion agents of Eu(Ⅲ)_β_diketone complexes have been synthesized by solid state coordination method.They emit strong red fluorescence(λem=619 nm) under UV light(λex=360 nm).The fluorescence increment effect of Gd3+,La3+,Y3+have been discussed.The additive amount of Gd3+ has been optimized.The composition of the rare earth organic light conversion agents determined by elemental analysis are Eu(TTA)3·phen·H2O and Eu4/5Gd1/5(TTA)3·phen·H2O.It has proved that the solid state coordination synthesis method has advantages of conserving energy,achieving good yield,no solvent and almost no pollution.更多还原
