8-氨-基喹啉镉配合物溶液的荧光性质

Fluorescent Properties of Cadmium with 8-Aminoquinoline Ligand Solution

采用荧光光谱法研究不同溶剂对两种8-氨基喹啉镉配合物溶液荧光性能的影响。结果表明,在极稀溶液中,发光体结构发生改变,相对与固体配合物而言,溶液荧光波长均向短波位移;不同溶剂中溶液荧光强度和波长均有较大的改变,主要是溶剂极性影响所致;在所选溶剂中,乙氰溶液的发射强度最强,属最佳选择溶剂。

The influences of different solvents on fluorescent properties of two cadmium complexes with 8-aminoquinoline ligand solution were investigated by fluorescence spectrum.The results showed that structure of luminophor changed,fluorescence wavelength of solution shifted short wave comparing with solid ligand in dilute solution,fluorescence intensity of solution and wavelength had large change in different,that was caused by polarity of solvent,emission intensity of CH3CN was the strongest in all solvents,thus CH3CN was the optimal solvent.
