Rezumat

A new coordinate organic compound (COC) Eu(DBM) ₃ (Ph ₃ PO) ₁ H ₂ O was synthesized and investigated (DBM stands for 1,3-Diphenyl-1,3-propanedione and Ph ₃ PO for triphenylphosphine oxide). The size of obtained Eu(DBM) ₃ (Ph ₃ PO) ₁ H ₂ O powder nanocrystals is around 50 nm. Under ultraviolet light excitation, the material exhibits an abundant and pure red color photoluminescence (PL). The PL spectrum measured in the range of 500 - 750 nm has a number of narrow (atomic) emission lines with FWHM less than 10 nm, which are assigned to the energy transitions ⁵ D ₀ → ⁷ F _i (i = 0,1,2,3,4) in the 4f - shell of the Eu ³⁺ ion. PL experimental results and its kinetics were analyzed using the theory of Judd-Ofelt's parametric method and the characteristic parameters were obtained: the lifetime τ, quantum efficiency η, and transitions probability of electrical dipoles A _ij
