Abstract:
An europium β-diketonate complex with a dipyrazolyltriazine derivative ligand, Eu(TTA)3DPBT, has been incorporated into poly(methyl methacryate) (PMMA). The influence of temperature on its luminescence properties has been investigated. The fluorescence emission spectra and luminescence lifetimes showed temperature sensitivity. The analysis of the relative intensity ratio (R) of (5)D0 → (7)F2 to (5)D0 → (7)F1 transition and Judd-Ofelt experimental intensity parameters Ω2 indicated that the local structure and asymmetry in the vicinity of europium ions show no obvious change when the temperature is increased.
