- Аннотация: In the present work EuF3/TOPO nanoparticles with average diameter in range 3 - 10 nm and narrow size distribution were synthesized by decomposition of europium triflouroacetate complex in TOPO melt. The formation of europium fluoride nanoparticles was studied by 10 thermal analysis, TEM, ED, XRD and UV-Vis spectroscopy. The particles are characterized by Eu3+ bright pinkish-orange emission at the wavelengths of 580-700 nm corresponding to the D-5(J) -> F-7(2) transitions. The intensity of line corresponding to the to (5)D0 -> F-7(2) magneto-dipole transition exceeds the intensity of electron-dipole D-5(0 ->) F-7(2) transition, which confirms the formation of centrosymmetrical structure of europium fluoride. This system seems to be a promising luminescent material because of the possibility of energy transfer from trioctylphosphine oxide shell to the 4f(n)-states of europium with subsequent europium, line emission in orange region of spectrum.
