摘要:New two- and trivalent europium complexes with dithio- and diselenodiphenylphosphinate ligands (S2PPh 2 - and Se2PPh 2 - ) have been synthesized as precursors for nanoparticles. Two-valent europium compounds have been characterized via X-ray diffraction. Their photoluminescence properties have been studied as well. EuS colloidal nanoparticles have been obtained via the thermolysis of Eu(S2PPh2) n (n = 2, 3) in a hexadecylamine medium at 310°C. The average size of objects is found to be 4070 nm. As is established, the valent state of a lanthanide in the complex exerts no influence on the size of the forming nanoparticles or on the luminescence spectrum of colloidal solutions.
