Abstract:

A series of coordination organic compounds based on the trivalent Eu3+ ion were synthesized and optimized: Eu(o-MBA)3phen, Eu(DBM)3(Ph3PO)1•H2O and Eu(TTA)3(Ph3PO)2. The efficiency of the photoluminescence (PL) emission of these coordination compounds depend on preparation technology, specifically on the optimal choice of the ligands. The photoluminescence spectrum measured in the range 500 – 750 nm exhibits a number of narrow (atomic-like) emission bands with the FWHM less than 10 nm.
