This new complex with the formula of [TbL(NO3)](NO3)2·2H2O was charact-erized by elemental analysis, molar conductivity, IR spectroscopy and thermal analysis. At the same time, the luminescent property of the complex was also studied.展开更多
Two series of solid complexes of rare earth nitrates and picrates with the "back-to-back" terpyridine, 6′,6″-bis(2-pyridyl)-2,2′:4′,4″:2″,2′″-quaterpyridine (L) have been synthesized.

These complexes have been characterized by elemental analysis, conductivity measurements, thermal analysis and IR spectroscopy. At the same time, the luminescent properties of the Eu(Ⅲ) and Tb(Ⅲ) complexes were also studied.展开更多
