Synthesis, characterizations and luminescent properties of terbium complexes with methoxy derivatives of 2'-hydroxy-2-phenylacetophenone

The complexes Tb(L(1))(3).2H(2)O (I) {where L(1)=2'-hydroxy-4'-methoxy-2-phenylacetophenone}, Tb(L(2))(3).2H(2)O (II) {where L(2)=2'-hydroxy-4'-methoxy-2-(p-methoxyphenyl)acetophenone}, Tb(L(3))(3).2H(2)O (III) {where L(3)=2'-hydroxy-4',6'-dimethoxy-2-phenylacetophenone} and Tb(L(4))(3).2H(2)O (III) {where L(4)=2'-hydroxy-4',6'-dimethoxy-2-(p-methoxyphenyl)acetophenone} were synthesized and characterized by IR spectroscopy, TGA/DTA and elemental analysis. The qualitative analysis of the complexes to detect the presence of terbium has been performed by energy dispersive analysis (EDAX). The synthesized complexes on exposure to UV light (354 nm) emit green luminescent with main peak at 546 nm. The complexes emitting bright green colour might be promisingly applicable for optical devices and solid-state lamps for general illumination purposes.
