We have previously studied the capacity of lanthanide ions to form complexes with the cyclic ..beta..-diketone, 2-acetyl-1,3-indanedione (AID). The complexation was studied spectrophotometrically for neodymium and erbium ions relative to change in the absorption bands corresponding to hyperfine transitions. The pH-potentiometric method was used to find the stability constants of the lanthanides with AID. The IR spectra of the coordination compounds of several lanthanides with 2-acetyl-1,3-indanedione and the thermal stability of these compounds were examined in our previous work. We found that the complexes of 2-acetyl-1,3-indanedione and 2-benzoyl-1,3-indanedione (BID) display strong luminescence upon their irradiation with ultraviolet light. The analogous compounds of samarium, terbium, and dysprosium have only weak luminescence. We carried out a luminescence study of the complexation of europium with 2-acetyl- and 2-benzoyl-1,3-indanedione.
