摘要
The fluorescence of Sm-dibenzoylmethane (DBM)-diphenylguanidine (DPG) system was enhanced by about two to three orders of magnitude when it was excited in the presence of Gd in ethanol-water solution. The excitation and emission wavelegths were 390 nm and 652 nm, respectively. The fluorescence intensity was a linear function of the concentration of Sm in the range of 1.0x10(-9) - 2.0x10(-6) M. The fluorescence mechanism of the system is discussed.
