摘　　要：合成了 Yx Eu1-x(phen) 2 Cl3· n H2 O、Tbx Eu1-x(phen) 2 Cl3· n H2 O(x=0、0 .2 5、0 .5 0、0 .75 )固体配合物 ,并测定了红外光谱、荧光发射光谱 。A series of mixed rare earth complexes of o-phenanthroline with europium,yttrium,terbium and dysprosium were synthesized by the reaction of trivalent rare earth chloride with o-phenanthroline in 95% ethyl alcohol.The composition is expressed with the general formula Y_ 1-xEu_x(phen)Cl_3·nH_2O?Dy_ 1-xEu_x(phen)Cl_3·nH_2O?Tb_ 1-xEu_x(phen)Cl_3·nH_2O(x=0.00,0.25,0.50,0.75,1.00).The complexes are characterized by IR spectra and fluorescence spectra.
