Abstract
Stable Eu3+ doped single-layer rare-earth oxide nanosheets sol were successfully obtained via exfoliation of layer Y(1-X)EuxOBr 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.
