- •
Energy-transfer mechanism from Dy3+ to Eu3+ is quadrupole-quadrupole interaction.
- •
Tuning the color emission of Sr3Y(PO4)3: Dy3+, Eu3+ samples based on energy transfer.
- •
The critical distance between Dy3+ and Eu3+ is 15.22 Å.
- •
The color temperature of Sr3Y(PO4)3: Dy3+ is tuned via the doping of Eu3+ ions.
- •
The decay life time of the Dy3+ decreases due to the energy transfer.
