Transparent Layer Derived from Layered Europium Hydroxide Sensitized with 2-Thenoyltrifluoroacetone
In this study, we present a novel layered material (LEuH-TTA) consisting of layered europium hydroxide (LEuH) and organic sensitizer 2-thenoyltrifluoroacetone (TTA) in a simple and environmental benign way and it was characterized by FT-IR and XRD. The luminescence intensity of LEuH-TTA
increased significantly after modified with TTA, almost 8 times that of LEuH at 612 nm. The luminescence behavior of LEuH-TTA was investigated by luminescence analysis, the results showed that red emission is caused by energy transfer from the TTA ligand to the coordinated Eu3+
ions. Furthermore, the thickness of luminescence film was measured and the SEM showed that it is about 1 μm.
