镧系离子与某些有荧光或无荧光的有机化合物配位后,有机配体能吸收紫外光并将能量传递给稀土离子,然后发出镧系离子的特征荧光,这就是人们熟知的“稀土敏化荧光”。这种敏化荧光具有stokes位移大、发射镧系离子的锐线发射光谱、荧光 Lanthanide ions and some fluorescent or non-fluorescent organic compounds coordination, organic ligands can absorb ultraviolet light and energy to the rare earth ions, and then emit the characteristic fluorescence of lanthanide ions, which is well-known “rare earth sensitivity Fluorescence. ” This sensitized fluorescence has a large stokes shift, emits a sharp emission spectrum of lanthanide ions, fluorescence
