Europium monophthalocyanine Eu(acac)Pc, europium monotetranitrophthalocyanine Eu(acac)Pc(NO{sub 2}){sub 4}, and heteroleptic europium tetranitrobisphthalocyanine Eu(Pc)(Pc(NO{sub 2}){sub 4}) are synthesized. The spectral characteristics of the phthalocyanine complexes in the visible and near-infrared regions are studied. The photoluminescence spectra are recorded. The luminescence bands are detected in the regions 450-500 nm (S{sub 2} {yields} S{sub 0}) and 670-730 nm (S{sub 1} {yields} S{sub 0}). The peaks are attributed to electronic transitions in the organic ligands.
