A novel red emitting polymeric complex poly(styrene-co-glycidyl methacrylate)-Eu(TTA)2(Phen) (PS-co-PGMA-Eu) as a directly film-forming phosphor was synthesized by the technological means of polymerization and subsequent coordination using Eu(TTA)2(Phen) as the complex precursor and poly(styrene-co-glycidyl methacrylate) (PS-co-PGMA) as macromolecular ligand. The synthesized polymeric phosphor can...
A new bi-color flexible remote phosphor film was prepared to gain remote white LEDs with high luminous efficiency, low color temperature and high color rendering index. The research results indicate that the proposed bi-color phosphor film with yellow and red phosphors at mass ratio of 12:1 generates pure white light as simply encapsulated into 1Watt blue LED bead, which shows average luminous efficiency...
