Preparation and luminescence properties of ormosil material doped with Eu(TTA)3phen complex

The europium complex, Eu(TTA)3phen (TTA=thenoyltrifluoroacetone, phen=1,10-phenanthroline) was successfully doped into organically modified silicate (ormosil) matrix-SiO2/(VTMOS+PMMA) (VTMOS=vinyltrimethoxysilane, PMMA=polymethylmethacrylate) via sol–gel process, and the luminescence properties of the resultant ormosil composite phosphors [ormosil: Eu(TTA)3phen were investigated compared with those of the pure Eu(TTA)3phen complex powder.The ormosil composite materials incorporated with Eu(TTA)3phen show the characteristic red emission of Eu3+ ion. The Eu3+ possesses fewer emission lines and longer lifetime in the hybrid phosphor than in the pure Eu(TTA)3phen complex. This has been explained from the viewpoint of the surrounding environment where the Eu3+ ion lies.
