苯甲酸稀土(Dy,Y)甲基亚砜配合物光致发光性的研究

SYNTHESIS AND FLUORESCENCE OF COMPLEXES OF RARE EARTH(Dy-Y) BENZOATE AND DIMETHYL SULPHOXIDE

合成了系列苯甲酸-镝-钇二甲亚砜混合稀土配合物,在室温下测定了固体粉末的荧光激发和发射光谱.结果表明DyxY1-x(C6H5COO)3(CH3SOCH3)(x=0.10～1.00)中部分Dy3+离子被Y3+离子取代,Dy3+离子的特征荧光发射强度得到较大提高.

A series of solid-powdered complexes of mixed rare earth ( Dy-Y) benzoate and dimethyl sulphoxide have been synthesized and characterized by means of elemental analysis,IR,and fluorescence spectra.In fluorescence experiments it has been found that the fluorescence emission of Dy3+ ions in pure DyxY1-xL3L is very weak.However,the fluorescence intensity of Dy3+ can be enhanced when a part of Dy3+ in DyxY1-xL3L are substituted for Y3+ ions.
