摘要：
New luminescent materials consisting of Eu3+ supported on silica gel functionalized with acetylacetone (EuAPG) and benzoyltrifiuoroacetone (EuBPG) showed a much more intense emission than Eu3+ supported either on silica gel (EuSG) or on silica gel functionalized with imidazole (EuIPG). The lifetimes of the Eu3+5D0 --> F-7(2) transition in the samples were determined. All the silica contained about 0.2-0.3 wt.% of Eu3+.
