通过荧光光谱法研究了铕(Ⅲ)、铽(Ⅲ)两种稀土离子对四(3,4-亚甲二氧基苯基)卟啉(T M PP)荧光强度的影响。在中性介质中,铕(Ⅲ)和铽(Ⅲ)与T M PP相互作用使T M P P的荧光猝灭。实验表明:以DMF为溶剂、420 nm为最大激发波长、655nm为最大发射波长时,T MPP的荧光强度和稀土离子对其荧光猝灭均达到最大值。 The fluorescence intensity of tetrakis (3,4-methylenedioxyphenyl) porphyrin (TMPP) was studied by fluorescence spectroscopy with two kinds of rare earth ions, such as europium (Ⅲ) and terbium (Ⅲ) In neutral medium, the interaction of europium (Ⅲ) and terbium (Ⅲ) with T M PP quenches the fluorescence of T M P P. The experimental results show that the fluorescence intensity of TMPP and the fluorescence quenching of rare earth ions reach its maximum when DMF is the solvent, 420 nm is the maximum excitation wavelength and 655 nm is the maximum emission wavelength.
