Luminescence Properties of Europium in Sorbates of the Complexes with Naphthoic Acid on Zeolite

A study of luminescence properties of sorbates of the europium(III) complexes with naphthoic acid and 1,10-phenanthroline on the zeolite of CaA-type that may be used as luminophores of the red color luminosity, has been performed.It was shown that the highest luminescence intensity in sorbate is observed upon the preliminary sorption of Eu(III) ion on zeolite following the treatment of naphthoic acid and 1,10-phenanthroline.The stability of sorbates to the temperature action was established (100°C, 2 h).
