In this work, the photo- and electroluminescence properties of new red phosphores based on europium complexes with carbacylamidophosphate (CAPh) ligands and additional aromatic ligands 1,10-phenantroline and 4,4"-bipyridine have been studied. Compounds Eu(L1)3(phen) (1), Eu(L2)3(phen) (2), Eu2(L1)6(i-prOH)2(4,4"-bipy)(3) and Eu2(L2)6(H2O)2(4,4"-bipy) (4), where HL1-2,2,2-trichloro-N-(dipiperidin-1-ylphosphoryl) acetamide, HL2 - 2,2,2-trichloro-N-(dimorpholin-1-ylphosphoryl) acetamide, were synthesized.Technology of europium complexes coating from solutions with different concentrations in different solvents has been developed. Experimental samples of light-emitting planar heterostructures were fabricated using the device architecture comprising an anode (ITO), a hole transport layer of 1,4-Bis(diphenylamino)benzene (BDB), a layer of complex and a cathode (Al or Mg). Another heterostructure configuration with a hole-transport layer of poly (3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) has also been investigated. The different types of planar heterostructures were prepared, and their current-voltage characteristics have been discussed.
