A series of single-phase Sr5(PO4)3F: Eu2+, Tb3+, Na+ phosphors have been synthesized by high temperature solid-state reaction. The photoluminescence excitation and emission spectra, concentration effect and energy transfer from Eu2+ to Tb3+ are investigated in detail. The work shows that there is an effective energy transfer from Eu2+ to Tb3+, where Eu2+ reveals an intense excitation band from 280 nm to 400 nm, matching well with the emission of n-UV chips, and Tb3+ emits an intense green emitting light.

A near Infrared (NIR) quantum cutting (QC) Sr3AlO4F:Tb3+,Yb3+phosphor was synthesized by the conventional high temperature solid-state reaction. The luminescence spectra both in visible (VIS) and NIR regions and decay lifetime curves of Tb3+have been measured to prove energy transfer (ET) from Tb3+to Yb3+. Quantum efficiency (QE) related to Yb3+concentration was calculated and the highest QE was found to be 135% hen Yb3+doped concentration at 20%. The present Tb3+and Yb3+co-doped Sr3AlO4F phosphor may be a promising candidate to modify the spectral of the solar light.

The phosphors Sr3B2O6: Ce3+, Sr3B2O6: Tb3+ and Sr3B2O6: Ce3+, Tb3+ were synthesized by the solid-state reaction method at high temperature. For the phosphor Sr3B2O6: Ce3+, the lowest 5d levels, the emission and the Stokes shifts of Ce3+ in the host lattice were identified. In addition, its concentration quenching process was also studied. For the phosphor Sr3B2O6: Tb3+, the f-d transitions of Tb3+ in the host lattice were assigned and discussed. Moreover, the energy transfer phenomenon between Ce3+ and Tb3+ in Sr3B2O6: Ce3+, Tb3+ was discussed. The emission of Tb3+ is significantly enhanced due to energy transfer from Ce3+ to Tb3+ when Ce3+, Tb3+ dopants were used together in Sr3B2O6.
