Photoluminescent properties and thermal stability of the complexes EuL3 · 2H2O, EuL3Phen and TbL3 · 2H2O (HL = PhC(O)N(H)P(O)(OCH3)2, Phen = 1,10 -phenantroline) have been studied in order to find new promising electroluminescent materials. A method allowing the fabrication of films from non-aqueous solutions has been developed for the studied compounds. The obtained films were characterized by means of atomic force microscopy and fluorescence spectroscopy. Experimental samples of planar light-emitting heterostructures ITO/BDB/EuWi3 · 2H2O/Al and ITO/PEDOT:PSS/Complex/Al + Ca, ITO/PEDOT:PSS/PVK/Complex/Al + Ca (Complex = EuL3Phen or TbL3 · 2H2O) have been created, and their current-voltage characteristics are investigated.
