The Sr3Y(PO4)(3): 0.05Sm(3+), Sr3Y(PO4)(3): 0.005Tb(3+), and Sr3Y(PO4)(3): 0.005Tb(3+), 0.05Sm(3+) phosphors were synthesized using a conventional solid-state reaction technique at high temperature and their photoluminescence properties under ultraviolet (UV) excitation were studied. We observed the UV sensitization of Sm3+ emission (565, 600, and 648 nm) by Tb3+ in Sr3Y(PO4)(3): 0.005Tb(3+), 0.05Sm(3+), that leads to a white light emission with the CIE coordinate (0.367, 0.312) of Sr3Y(PO4)(3): 0.005Tb(3+), 0.05Sm(3+) phosphor under UV excitation. The emission is a result of partial energy transfer from Tb3+ to Sm3+, which is discussed in detail in terms of the corresponding excitation and emission spectra.
