Preparation, characterization and photophysical properties of hybrid materials from rare earth complexes of phosphonato-substituted DOTAM derivatives

Europium complexes [Eu.L]X33 (X = SO3CF3, NO3) of (diethoxyphosphorylnaphthyl)-substituted DOTAM were prepared and incorporated into titania and zirconia inorganic matrices. Zirconia revealed an appropriate matrix to achieve an efficient sensitization of emitting lanthanides.
