The adulteration of the non- fluorescence lanthanum or gadolinium ions can enhance the fluorescence intensity of the complexes of europium,but only have little influence on the locations of the fluorescence characteristic peaks.

• La3+、Gd3+以不同比例掺杂Eu~(3+)配合物,在紫外光的激发下,Eu~(3+)荧光发射峰位置只有微小变化,但对其荧光发射强度影响较大。
