Abstract

Abstract:

Eu(Ⅲ) acetate and Tb(Ⅲ) acetate reacted with acetyl acetone at about 60℃ to synthesize two different rare earth β-diketone complexes. With the UV light illumination, the fluorescence of Eu(acac)3·3H₂O is dark red, while the Tb(acac)3·3H₂O is bright green. Results from infrared spectra agreed with the theoretical prediction. Through fluorescence analysis, we found these complexes are relatively better luminescent materials. These complexes presented good luminescent properties and thermal stability.

Key words: Rare earth luminescent materials, β-diketone complexes, Acetyl acetone, Characterization
