Fluorescence Enhancement of Europium-Doped Yttrium Oxide Nanosheets Modified by HTTA

Abstract:

Stable Eu³⁺ doped single-layer rare-earth oxide nanosheets sol were successfully obtained via exfoliation of layer Y_(1-X)Eu_xOBr in n-butanol solvent. After β-diketones modifying, novel inorganic/organic luminescent hybrids were successfully synthesized. At the mean time we discovered that the main charge transfer (Eu-O) excitation bands in nanosheets were replaced by more efficient π-π* electron transition excitation band s of the organic ligands in the hybrids. The emission bands of the ⁵D₀-⁷F₂ electric dipole transition in hybrids were enhanced greatly.
