Enhanced luminescence of novel rare earth complexes Eu(3,5-DNBA)3Phen in nano-TiO2.


PMID 19062332

Abstract

Eu(3+) (or Tb(3+)) 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-vinylcar-bazole):RE(3,5-DNBA)(3)Phen:TiO(2)/Al was fabricated. The nano-TiO(2) has been used in the luminescence layer to change the electroluminescence property of RE(3,5-DNBA)(3) Phen (RE=Eu(3+)or Tb(3+)).
