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) 3Phen: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+).
