文摘
- •
Enhanced green-emitting NaGdF4: Dy3+, Tb3+ nanophosphors have been prepared.
- •
Dy3+ has comparatively intense absorption in n-UV region compared to Tb3+ ions.
- •
Dy3+ ions can absorb n-UV light and transfer excitation energy to Tb3+ ions.
- •
The energy migration of Dy3+-Tb3+ is dipole–dipole mechanism
