文摘
- •
Doughnut-like EuF3 aggregates were fabricated.
- •
The EuF3 particle surface can be modified by different methods.
- •
Dbm− and Phen form the surface complexes at the surface modification processes.
- •
Surface modification with Dbm− and Phen leads to luminescence intensity enhancement.
- •
Energy transfer in surface complexes makes a main contribution to the enhancement.
