  Excited State Dynamics of Organo-Lanthanide Electroluminescent Phosphors:  The Properties of Tb(tb-pmp)₃ and Gd(tb-pmp)₃

  摘要：

  The excitation energy transfer rates between the excited states of a Tb(III) complex containing the ligand 1-phenyl-3-methyl-4-(trimethylacetyl)pyrazol-4-one, are described. Energy transfer rate constants are derived from time-gated and time-correlated single photon counting measurements. Comparison with the analogous Gd(III) complex shows that there is efficient intramolecular energy transfer from a singlet state of the ligand to excited terbium f-electron states. There is no evidence of bi-exciton annihilation in these materials, even at very high exciton densities. The use of this complex as the active medium for electroluminescent device applications is addressed. We note the particular properties of the ligand which make it suitable for this application and suggest possible improvements.

  Photoluminescent compounds are described having no-ligand. These have formula (I) in which Ln represents a lanthanide ion, each of X, Y, and Z, which may be the same or different, represents hydrogne, an optionally substituted aromatic group or an optionally substituted aliphatic or cycloaliphatic group, such that at least one of X, Y and Z represents a said aromatic group which is conjugated with the pyrazolone ring system and such that when X or Y represents a said group, said group can optionally be attached via a hetero atom. These compounds possess useful electroluminescent properties such that they can be used in electroluminescent devices.

  本文描述了无配体的荧光化合物，其化学式为（I），其中Ln代表镧系离子，X、Y和Z分别表示氢原子、可选取代的芳香基团或可选取代的脂肪族或环状脂肪族基团，其中至少一个X、Y或Z代表与吡唑酮环系统共轭的芳香基团，且当X或Y代表该基团时，该基团可通过杂原子连接。这些化合物具有有用的电致发光特性，因此可以用于电致发光器件中。
