Luminescent Eu(III) hybrid materials for sensor applications

In this work we use the sol-gel technique to develop different luminescent Eu(iii) porous materials from a bis(trialkoxysilyl) organic precursor synthesized from the amide of the DPA (2,6-pyridinedicarboxylic acid) with APTES (aminopropyltriethoxysilane) in the presence or absence of the non-ionic s...
