SPECTRAL-LUMINESCENT PROPERTIES OF COMPLEXES OF LANTHANIDES (III) WITH 4-ACYLPIRAZOL-5-ONES

Abstract

The optimal conditions for complexation of lanthanide (III) ions with 1-phenyl-3- methyl-4-formyl-pyrazol-5-one (L) and its derivatives, the molar ratio lanthanide:ligand in the complexes and their spectral-luminescent properties were established. It is shown that the introduction of additional ligands, organic solvents and surfactants increases the luminescence intensity up to 100 times.
