以吡嗪－2，3－二羧酸（H2PDOC）、TbCl3·3H2O和EuCl3·3H2O为原料，采用溶剂热法制备系列固体粉末发光配合物[（Eu（1－x）Tbx）2（PDOC）3·3H2O]（x＝0（1），0.2（2），0.3（3），0.5（4），0.7（5），0.8（6），1.0（7））。对系列配合物通过元素分析、红外光谱等方法进行了基本表征。在室温下研究了其固态荧光性质，结果表明：该系列配合物（除Tb2（PDOC）3·3H2O）均具有Eu3＋离子特征荧光，系列配合物中Tb3＋对Eu3＋的荧光强度有敏化作用，Eu3＋对Tb3＋的荧光强度有淬灭作用。%A series of europium and terbium doped complexes (Eu(1 -x)Tbx)2(PDOC)3·3H2O(x=0 (1),0.2 (2),0.3 (3),0.5 (4),0.7(5),0.8 (6),1.0 (7))were synthesized with the reaction of trivalent rare earth chlorides with pyrazine-2,3-dicarboxylic acid under hydrothermal conditions.These complexes has been charac-terizated by elemental analysis,infrared spectrum method.The solid fluorescence properties of these complexes had studied at room temperature.The results showed that for these complexes the Tb3+ion has sensitization effect Eu3+ion,and the Eu3+ion has fluorescence quenching effect Tb3+ion.
