Enhanced luminescence of novel rare earth complexes Eu(3,5-DNBA)3Phen in nano-TiO2
摘要:
Eu3+ (or Tb3+)of 3,5-dinitrobenzoic acid and 1,10-phenanthroline ternary rare earth complexes were synthesized and characterized by thermal analysis, infrared spectroscopy, elemental analysis and fluorescence spectroscopy. In this study an organic-inorganic combined device indium tin oxide/poly(N-vinylcarbazole):RE(3,5-DNBA)(3)Phen:TiO2/Al was fabricated. The nano-TiO2 has been used in the luminescence layer to change the electroluminescence property of RE(3,5-DNBA)(3) Phen (RE = Eu3+ or Tb3+). (C) 2008 Published by Elsevier B.V.
