Incorporation of europium(III) compounds: the oxide and dibenzoylmethane ch
elate (Eu(DBM)(3)) into zirconia xerogel glasses resulted in luminescent ma
terials in which the DBM chelate was the most efficient in luminescence int
ensity. The luminescence intensity was even stronger in hybrid xerogels pre
pared from zirconium tetrapropoxide and 3-glycidoxypropyl-trimethoxysilan.
